on a s4 harness do the diffrents in high/low injectors matter or is the harness the same? and a noobed question... are there any diffrences in jspc vs aspc harnesses. about to buy one so i needed to know

 

the harnesses are different, there is a resistor pack on the low impeadence systems (as well as other minor placement issues).

and Jspec harnesses don't even come in the same hole in the firewall... they are radically different

 

ok then i have to get a jspc harness for my motor then.... wow that's so ******* stupid.... i so witch i had a aspc right now

or can you some how run a aspc harness on a jspc?

 

well since the Aspec front harness runs through the same hole in the firewall as the Jspec engine harness would normally use, you would probaby have some issues

 

i think you are thinking i have a jspc car. i have a aspc gxl body and need a harness for my jspc 13bt that in the car.

the mech said i had 15900 blue ionjectors so im having a friend check them inless there some kind of stock injector i never heard of.

 

So either modify your existing GXL harness or get a USspec Turbo harness put onto that Jspec

 

I used a jspec harness. I wouldn't do it again but it can be done...

It will stretch to the Stock ECU location but you can't route it exactly like the US Spec one. Once you are ready to pass it through the firewall, it becomes pretty obvious how to route it.

The main issue with the jspec harnes is that it has no wiper harness. You will have to extract your old one from your NA harness and wire it in. Not a big deal.

You will also lose your cruise control wiring - but I elected to delete it.

The next issue is that you will lose your coolant temperature gauge sensor wire. You will have to run another one from the sender to the yellow and white wire on the body side clip of the emissions harness. Its pretty easy though - especially since you have the wiring exposed anyway.

 

well if i can run a aspc i'll just get one so it fits right and runs right and figure out with injectors i have
