Re: EFI connection OBDII 4X swap
Harness was made for a 85-92 third gen with tpi?
Did you buy the harness new?
Ya my bad thought it was the ls style conversion...
Still im interested., but confused that efi connection doesnt advertise the single coil conversion...

Re: EFI connection OBDII 4X swap
yes and yes. this is this first style of the LS conversion more of a vortec LS hybrid. Im not sure why they dont advertise it my guess is the 24x swap seems more appealing? But to me you still have the LS1 PCM that can be tuned by yourself or just about any dyno tuning shop and thats what everyone is after.

Re: EFI connection OBDII 4X swap
Do you have a more detailed description of how he built the harness?
Also im assuming they gave somewhat of an instruction for install?
Maybe shoot me an email with some more photos and if you can answer the previous two questions
