Hi everyone I’ve recently swapped a 96 4.0 engine/ecu/wiring into the 86 B2. Motor runs so i decided to get the obd 2 plug wired in. I’ve got the correct wires plugged into the ecu harness (purple, pink/blue, tan/orange) and I have 12v supplied to the orange wire, and the black, and black/white wires are grounded to the chassis. My obd2 scanner powers up but cannot connect. It says interface connected, attempts numerous protocols, and then gives up after it can’t find any that work.
There is 1 wire a light blue/white that I could not find where to hook up, but from what I’ve read it is for auxiliary items (abs, etc) so I don’t see it as a concern. But then again I’ve read it’s the J1850 bus+ wire which I see my scanner attempt to connect to that protocol. Wondering if that might be my issue. Another thing According to the diagram I found, the black/white wire should be signal ground and the black should be chassis ground. I cannot find anywhere in my engine control diagram where the black/white wire would go, only the pk/blu, ppl, and tan/org.
Any ideas? My scanner works fine in everything else I’ve used it on.
