I'm using an 89 harness to put a 5.0 into my 86, almost done, except a couple hold-ups. There are 2 connectors on the driver's side, a grey 8 pin and black 8 pin (could be brown, it is faded) pictures are below. I am running NO A/C on this car, mechanical gauges that are all done and wired, but according to some diagrams these wires for the connectors are to do with my TFI and dizzy, so I want to make sure they are right in order for the car to run. This is the one (above) on my 89 engine harness but there is one on my 86 harness that goes through the driver's side firewall into the engine bay that is identical in shape and the wire colors are mostly the same, too. The one on my 86 is below: Any help where these go would be great. Is it possible that during the years, they changed the male/female connector side? If that's the case, I can easily repin an 8 pin connector so that they plug right up as they're supposed to connect. They're basically the same plug but one is on the harness to go into my car on the driver's side firewall and one is attached on the 89 main engine harness. They are both female connectors. Below is the grey connector, which is also on the 89 main engine harness: There are no male connectors for these that I see...they are just hanging there but I KNOW with this many wires, they have to go somewhere. This is the last step of my wiring then I can test start my car! Any help would be great.
