Engine harness qeustion
hey i was looking to get a engine harness shortly, ( since mine in the car is a hackjob , fuel injector wires cut , maf cut) i was wondering if i needed only the passenger side wiring harness ( the one that connects to the ecu from the pass side ) i would like to know also if that harness would replace these plugs also , maf , fuel injector connectors, bac valve connector and other lil connectors on the engine ? or would i need the harness that goes thru the drivers firewall ? sorry for the rush but i need to know before the end of the weekend .

how could you question K-Tune like that you fokkin awshole? haha just kidding.
Anyways, the engine harness is what you need. It connects to the ecu and a few connectors behind the passenger kick panel and goes through the passenger side firewall to the engine where it connects to the afm, boost sensor, then goes to the engine. In order to replace it you'll need to remove the upper intake manifold, so you need the gasket that goes between the upper and lower manifolds. GL!

Just to clarify, it's actually called the emissions harness or EM harness for short. If you look though the FSM wiring diagrams, you'll see the EM reference on just about all the wires at the ECU & also at the front harness connection under the dash. The engine harness is completely separate, and is actually on the driver-side of the bay.

I don't think he has any of the names correct, so my advice would be to ask for a picture. It's probably going to be what he's calling an "engine wiring harness". Most people don't know the names from the FSM.
The correct names & some things they go to are:
Emissions harness - ECU, engine sensors, front harness connector
Front harness - instrument cluster connector, many things behind dash & up to front of car
Engine harness - CAS, alternator, relays
Instrument cluster harness - cluster
Rear harness - tail lights, fuel pump
Door harness(s) - window switches, speakers, alarm sensors

You need the engine harness that Really is going to be for your Series of engine.
you need either an S4 for your s4c or an S5 for your s5.if you are running an S4,you can use Different injectors,(lo or hi.) depending on what ecu you have.
the S5 has different injector connectors and an electric OMP to plug in, so really it can't be used on an S4 Engine.

thanks for the correction rotaryrocket88, I didn't look at the FSM.
Anyways, when you buy this harness aftermarket on this forum or on ebay or whatever will most likely be labeled 'engine harness'.
