A a question or 2
im working on my LS conversion harness (for a 1989 305 TBI RS) and would like to have a couple things cleared up:
A) one how to has this wire going to power for the fuel pump:
but another how to doesnt have anything going to it. i have a fuse box that the fuel stuff goes to so im guessing the red wire can be cut out? <--Blower motor relay connector; do not cut
B) concerning fuel, what should i connect G4 (c100 bulkhead connector on driver side), and E6 to? they are tan/wht and red (red/black on inside of the car) respectively.
c) what should i do about the fuel pump relay behind the kicker panel on the driver side? its got a green/wht, green, and 2 yellows comming out of it but cant find ANYTHING in the wiring diagrams about it.
d) considering i have a fuse box to have engine/ignition/etc on a separate circuit so id like to know how much of the wiring/fusebox i can take out.
ive been reading through the stickies but my issues seem to be a little more specific and appreciate the help. =)

Re: A a question or 2
Ok, seems like you're a little mixed up but on the right track
The simplest path is to leave your fuel pump relay intact from your original harness. You only change which ECM controls it with the new engine/wiring
b) G4 goes directly to your fuel pump. Either leave your stock wiring alone or splice your new relay output to this wire
I do no know what E6 goes to as I deal in 90-92 wiring exclusively
c) That is not a fuel pump relay, its the starter kill relay. It is part of the VATS system and needs to be bypassed in order for your car to start. You can ground it and have a redundant relay or bypass it by connecting the two heavy gauge wires
d) Youll have to identify each circuit and remove/retain at your own discretion. Every swap is different, especially in the wiring aspect

Re: A a question or 2
I used the c207 connector, the one the tpi ecm, used to turn on the pumps... wasn't to hard to find which one. Use a meter red/black are switched 12v, and one of the wires using a with a jumper will turn on the fuel pump. ( I had a diagram = safer)
I am not sure if tbi c207 had control for the pumps there... Sounds like a good place..lol
