It's a automatic vehicle.
Expert:  Eric replied 26 days ago.

HI,

I will have to opt out and see if another expert can help you as I have connector views but no corresponding pinouts telling the wire color or what it goes to.

The fuse box in question is located on the left inner fender. It's 1994 box on a 1992. I have three wires on the vehicle that do not have a match. The White plug with 8 plugs slots, has white wire located in slot eight from 92 no matching wire on 1994 fuse box. The black plug has two small white wires this plug also has 8 slots wires are in 1 and 8. What does these wires operate. They plug well plug in the old fuse box and the 1994. But the car would not crank over. So I went to the junk yard and cut the plug and wires from a 1994. At first look, the wires match find. The same for the ECU, I understand that some wires will not be used do to passenger air bags. On the ECU I have red/blue with silver dots, Lite green/red with silver. Green/red with silver dots and black/white wire with silver and black white don't have a matching color on the 1994 ECU. All should be connected. Again I understand that the 1994 ECU will have wires that are needed. But the wires on the 1992 should be connected for the vehicle to operate. What do I do?
