96 4.0 to 90 Bronco II Swap Guidance


We'll it's been long enough that I should follow up on this swap. I got the engine started the other day. Took for a short drive and this thing has so much more power now! Definitely worth it. I was able to use my complete Bronco II headlight harness and power distribution box. Used the explorer for everything else. About 90% plug and play.

I did, however have to make an temporary adapter plug on the drivers side to connect the red/green wires (EEC and fuel pump relay) and orange/black (o2 sensor heat). I couldn't just swap of pins around since I ended up with either two female or two male pins together. I have two problems I need to track down. My Tachometer and coolant temp gauges do not work. I have a feeling I need to find the correct color wires on the drivers side to reconnect, just haven't figured them out yet. Here's a couple pics (hopefully they work).
