Hey Guys,

well.. i have almost my car ready, but there are some connectors which i dont remember what they are for i havent found anything in the FSM and Wiring.. so i hope that i find somebody who can help me out.

Here my taken pictures.

First off, i want to know if the engine harness is installed correctly (under the piping), and please look at the picture carefully, mayb youill find something what i have done wrong!
Are the Injector-Connectors right??



here are all the connectors i want to know, colorcoded below you see detailed pictures of the connectors.

please, tell me what connector which color is, and where it should go.. i have no clue. The red one i guess.. is knock sensor right?

here we go.









ok, is this grounding right or wrong??



and is the watertempsensor connected right?




i really need all help you can offer, i appreciate each reply.

Thank you very much!

Regarding your last picture, that's not a water temp sensor. IIRC that's an oil pressure sensor. I could be wrong, but I'm 90% sure it's for oil and not water.

injectors are hooked up wrong

Dude, you got a lot wrong there. ****, let's see...where to start.

Pic 1...injectors. There is a front "branch" of the harness and a rear "branch". You currently have the rear branch connected to both secondary injectors. Wrong. The rear branch feeds the rear injectors...the short connector, to the primary rear, the longer one, the secondary rear. Same for the front.

Pic 3. knock sensor...should be on the front rotorhousing above the trailing sparkplug (s5 engines) or the intermediate iron at the base of the oil filler neck (s4 engines)

Pic 4. Coolant temp sensor plug, rear iron below oil filter, the sensor that sticks out/up at an angle right beside the rear trailing plug.

Pic 5, bac valve, upper intake on passenger side.

Pic 6, aux. efan thermoswitch wire, goes on the gray sensor on the back of the waterpump housing, below the green sensor. Not critical; activates the aux. e-fan when temps get too high. Only AT and turbo models had the fan.

Pic 7, ACV plugs...air control valve, lower intake, passenger side, big triangle looking deal. Color coded plugs on both ends.


Pic 8, yes that ground clip goes on the bracket with a 10mm bolt...but it should be a clean ground at the base of the bracket and at the wire as well. You can also ground this to the TPS/throttlebody, or whatever...it's not critical.

Pic 9, no...you've connected the plug for the ground condensor to the coolant temp sensor. Run the coolant temp sensor wire as described above. The wire that you have there now, should go to the little black box (1/2" square) that bolts onto the slave cylinder. It is not critical, and has to do with the oil pressure gauge circuit. Most cars, the gauge will still operate without the ground condensor being plugged in.

red is knock sensor
green coolant temp
purple is BAC and black connector on same part of harness goes to oxygen sensor, not to alternator plug
yellow and blue are ACV connectors
brown is water thermo switch for electric fan (if you dont have the switch in the back of water pump, leave disconnected)

fix your harness position first, front part goes to front injectors+water pump, rear part goes to rear injectors

that ground can go anywhere on the block really. But on the block theres the support for the intercooler. you painted it black. Looks really nice by the way. well anyway i believe either theres a bolt under the support or on of the bolts holding on the support. make sure to go under the support so the ground is touching the actual support if it is that way. You do not want to ground it on the support it is paint black the paint is a insulator gonna cause resistance you dont want. So probably the block.. o and where you mount it you should scratch the paint off the block, just for good luck..

Phantomkid

your first picture looks like you have the ground attached under the support bracket. Anyway the FSM is in the FAQ section. You can reference the injector wire to which injector from there. unless someone konws i dont konw if its the same for s4, and s5.

i wanna see pics of this engine after its done!! : D
