C100 Bulkhead Wiring ?? C7/G4/G8 Specific
 

This is a 92 RS car. I have a few questions on wiring off the bulkhead. I know what most wires do and where they go. my questions are specific to these and a couldnt locate awnsers when searching. I am doing an LS1 swap using a Howell Harness. Its an 02 LS1/T56 going into a 92 RS which was originally a 305/5speed Car. Thanks for any help........jt

1) C7 Black/White Wire schematic says "Engine" with no other description. I followed the wire and it looks like maybe part of a ground but also went to what i believe was emissions wiring. Do I need to ground this or just cut it out completely.

2)G4 Gray Wire "Engine: Fuel Control" I believe this is for the fuel pump so is this where i need to hook the howell fuel pump wiring up at? The Howell harness already has a built in Relay set up and has one connector labeled fuel pump.

3) G8 Brown Wire "Starter and Charging System; Charging Coolant fans( Coolant Fan relay) Again The howell harness has the fans and relays built in so can i just remove this wire completely or do i need to keep it for some odd reason.

One last question while i'm at it. D4 and E4 are for the vehicle speed sensor VIN E (Yellow and Purple Wires) my harness came with the VSS wiring so before i cut these off i just want to make sure i dont have to do anything with these to make my speedo work. I indersatnd i have to do some wiring under the dash but i havent gotten that far yet.

Awnsered some of my own questions.

1) It is a ground, starter wont turn over unless its grounded. Engine still ran when i jumped the starter. Also messes with the guages when not grounded.

2) Yep, Its the fuel pump wire.

3) Still not sure what it does. Its hot with the key on so may come in handy for something.

Last part, VSS wires. Most likely wont need these wires but left them on there anyway. I will probably just tie them out of the way on the trans. Since i ran the back upo plights and the vss wires together.


Anyways the engine runs good, its nice and loud with no exhaust. Gotta work on the next......jt
