MAP Harness help

[jondee86]

Ohhhhh.... kaaaayyy then.... not likely that you will see one of those
plugs on the firewall Those are the ECU plugs, and an accessory plug
that should have a matching socket close by the ECU.

If the accessory plug on the loom doesn't match the one beside the ECU
you will have to swap the plugs and match up the wires. Your plug doesn't
match mine, so I can't help much. But for your information, I did identify
these items on my car as leading back to the accessory plug :

1. Wiper motor (3 wires)
2. Washer motor (2 wires)
3. Variable resisitor (1 wire) (used on AE86 without O2 sensor)
4. Spare plug on engine loom (1 wire)
5. Plug beside underhood fusebox (1 wire) (can't remember what it did)

AFAIK the accessory plug in your pic has nothing at all to do with the
plug on the engine side of the firewall as described above
