Justinsstang 2006 GT M90 Build Thread

Okay, so I did get the intercooler mounted after being crafty for a while. It doesn't look perfect, but I'm pretty sure it's going to work. It's secure and I think that's the most important thing.



On to the next step, and next problem lol. So The intercooler pump I have is missing a bracket. I have it mounted sideways because I just don't see another way to do it without ordering it. it's secure, but does anyone know if it's okay to have it mounted on it's side like this? I'm content with it as long as it will run fine, assuming the fender well will go back in okay after I install the bumper.
In the pic the piece on the side is the inlet, and the piece pointing up is the outlet (logically opposite lol).




Okay, so as long as it's okay that the pump is mounted that way, then we can move on to the real ball buster that I'm not sure what to do about.
After installing the intercooler pump, I went to do the wiring. The harness I have is missing a plug and I'm not sure how to wire it up. Here is a few hard to get shots of the plug on the intercooler pump




And here is how the wire is supposed to kind of look, can't really see it because it's from the instruction manual:


And here is how the wiring harness given to me looks:






Okay, gosh that took forever to upload all that and post lol. Basically I gotta get this wired up to run any time the key is on per Skwerl. He said he can't really help me with this part because he doesn't know about wiring, so I'm hoping someone has a clue because I sure don't lol.

I just remembered something. I had the busted up Afco dual fan intercooler and the wiring harness that went with it. Showed it to Justin (VMP) and confirmed it was the wiring harness for the Afco. Since you didn't need it and the Afco was trashed, I was going to throw it away. Justin kept it because it had several valuable relays and such in the harness. I'm guessing everything was tied in together and the connection you need was attached to that harness. I'll talk to Justin and he can check to see if that plug is there. If so, I'll get it to you.

One will be for power in, one for power out, one for ground, and one for energizing the relay. More than likely the two with terminals are for ground and power source. The other two should be for key on power that energizes the relay and power out.

You will have to figure out what is for what.

 

[justinsstang]

Okay, how do I figure out which is which? God I am clueless when it comes to wiring. here's the instructions: http://www.roushperformance.com/parts/manuals/Mustang-Supercharger-2005-2006-420112-manual.pdf
I'm on page 52, scroll down with the bar on the right until it says 52 next to it =P

The wiring harness is attached to the relay. Just trace the wire back and see what post it's attached to on the relay.

I pulled the relay to check but it doesn't have any labels such as (-) (+) etc.
Here's the pics, maybe you can tell what's what.


and the bottom number u couldn't see in the first pic

and a shot of where all the wires show so colors can be matched

 

[Mustangfan]

pole 30 is fused power(from Batt) 85 is your ground wire, 86 is the trigger (key on ignition source) 87 is your output (power to pump). Just look at what color wire on your plug is corresponding to poles on the relay.

 

[justinsstang]

Okay so the red30 is power, blue85 is ground, green86 is the trigger (key on ignition source), yellow87 is output (power to pump). Orange87A isn't used. Okay, so based on that, with wire ends like this how would I wire it up? Not sure why heatshrink is on the blue wire with it being ground.

I know where to connect the red power wire, I have to cut a wire out of a harness and solder it together to it. Blue I can just ground anywhere to the frame.

green86 - trigger (key on ignition source), yellow87 - output (power to pump), not sure where to put those wires.
I'm guessing yellow is the one that's supposed to have the connector piece attached to the end that plugs in to the pump.
And where would I connect the green tell it to turn on when I turn the key on? Thanks mustangfan

 

[Mustangfan]

Red (30) needs to go to your battery, get a 30 amp inline fuse (it does not wire into your harness). I'm not sure what to use for key on ignition, I think I talked into my noise suppressor for the trigger. Once you get the connector for your pump you would take the hot wire and connect it to your output wire, then take the negative and ground it to chassis.

Do a search for key on ignition in the search feature to help with your trigger wire. The only thing proprietary about that harness is the plug that goes into the the pump, the rest just a standard relay with wires. Basically your applying battery fused battery power, then grounding the relay, then tapping into a key on ignition source to switch on relay, then your sending the power out of the relay into the pump.

What hot wire would connect to the yellow output? I figured I would just slide the yellow in the connector piece and then push the connector in to the intercooler pump... Now I'm super confused lol

Pages 52 & 53 tells me to cut a wire out of a connector and solder it to this harness, pretty sure I'm supposed to. Only makes sense to me that it's the red one because it's the only sort of long one on the harness.

Wondering if I should just order a new harness if Justin at VMP doesn't let skwerl know something about that old one tomorrow. But then I wouldn't know which harness to order because it's off a 2010 kit... so don't know if I would need to order a harness for a 2006 or a 2010... lol. Hopefully Justin has something

 

[2005Redfire6]

I just found this pic as I woke up and was eating breakfast before I headed out there to try to figure it out.
I'm not sure if it will help me, or help you help me yet because it's on a 2010 but here it is.

You can kind of see how its supposed to mount on the 2010. If I mount the top to the impact bar it will hang way to low I think

Ahh I see, yeah my heat exchanger was about half of that size as well in height. Glad you got it figured out!

 

[Mustangfan]

Dude, your overthinking this. There's no reason to wire into the cars harness, just wire it like a standard relay. Honestly not being a jerk, but this type of wiring is very simple- you want the pump to run anytime your car is on. If your running a relay for the pump it should always have a fused power wire from battery. If you can get a connector on the pump you might not need the plug for it.

I'm not overthinking it I'm just following directions xD
Why would they tell me to cut that wire and solder it to this harness if I didn't need to, not sure what the wire I'm supposed to cut and solder goes to in the first place. I understand what you're saying but I feel like I should follow Roush instructions, there's probably a reason that wire needs cut from the harness other than to power the IC pump... maybe to disable something else while also giving power to the IC pump? What do you think?

 

[skwerl]

I'm not getting involved because I know even less about electrical than Justin, but in principle I agree with Mustangfan. IMO Roush used a specific wire in their instructions because that is easier than saying 'pick any keyed power source you like'. But really, any decent radio installer type person can safely and reliably hook it up to a keyed power source for you.

The plug for the pump is on its way.

 

[justinsstang]

Wonder what the wire I'm cutting out of the harness is used for then... Hmm maybe I'll give Roush a call and see. I'd definitely feel more comfortable doing it mustangfans way than cutting in to the harness when I don't even know what the wire I'm cutting is for lol

 

[Mustangfan]

They have you cut into the harness is bacause I think they are having you run a hot wire directly to the pump with no relay, or there using it as a trigger. When I installed my Saleen kit, the directions were saying to wire the pump into the passenger compartment and to splice it into the harness.

Trust me you do not need to cut into the harness, it's totally unecessary. Not to be a jerk, however I would suggest that you defer the wiring to someone with more experience than you.

 

[bcb06gt]

I would not splice into any of my stock wiring. Like mentioned about, use a 30amp inline fuse to the relay from the battery or the main lug at the engine fuse box. Then I would use a "add a circuit" in the engine fuse box for the trigger wire. You could add another fuse after the relay, 10 amp, for the pump. I run my pump this way AND fans on my heat exchanger off the same relay with their own fuse. This way, the fans blowing a fuse can't take my pump out. I added my own fans so no fancy harness or connectors.

Also, put an ohm meter between the battery wire and ground to make sure those are across the relay coil. You should have almost 0 ohms across the coil. Just seems as though two eye loops would be to a ground lug and power lug.

So confusing lol, wish I had a visual to see how this thing should hook up

 

[bcb06gt]

Need a hand sketch?

Google Bosch style relay wiring diagram. Tons of different diagrams. If you were close by I could have it done in 20 minutes
