I'm about to change the hoses on my fuel injector, and was thinking of replacing the harness as well. I see SNG carries them, but I also know that several people have made their own harnesses. I'm considering doing this, using larger gauge wire as well, and getting things up out of the V, but I'm wondering what kind of connectors are needed, and where can one source them? My experience with wiring has been focused on boats, so I'm good with a crimper, but I don't know much about these systems.

SNG also lists an engine wiring harness, but this is "special order"... so I might as well consider that as well, if I can source the connectors.

I'm probably best off just going with SNG, but I thought I'd ask first. Thanks!

 

These are the boys, Bosch EV1 connctors.
You need the ones, like these, with the half moon cutouts otherwise they will not go on the injectors in our cars. You can buy them with or without pigtail wires already fitted.

 

Hi, Greg! Would these be the same for a 1987? I am planning on replacing my harness soon also, figured I might get stocked up on the connectors!
Thanks!

They're what I used on my '87. Although I think I got them from Digikey and had to crimp them myself. But they're the same connector certainly.

 

Thanks Greg! Bosch EV-1, with half moon cutouts. Got it!
