BEAMS update, August 10 Options

[Outsider]

I guess it's time for another update. I have been very busy at work trying to finish a contract(should be done this weekend) so not much has been done.

Now that the harness has been modified to fit the car it is time to go through the connectors, pin by pin. I have finally recieved a BEAMS engine wiring diagram thanks to Mario at Toysport. So many wires, so many connectors. Where to start? I choose to break the project into systems as they are drawn in my BGB wiring manual.

• Charging
• Starting
• Air Conditioning
• Cruise Control
• ABS
• SRS
• Ignition

I will only work on the connectors that tie into the body harness beside the ECU and the engine bay fuse box. Any connectors that go to the ECU or anything on the engine I will not touch.

CHARGING

exact match, no changes required.

STARTING & IGNITION

One wire was missing on the BEAMS harness. Connector IJ1 was missing pin 17. Turns out this wire goes to the clutch start switch. Easiest thing to do was remove it from my old harness. I pull pin 17 from the connector and start to unwrap the old harness. I discover that it splices in about 6 inches away from the plug. Excellent I say. Problem solved. Wire has been added.

AIR CONDITIONING

This system requires looking at 2 connectors.

IM1 - goes to A/C computer.(7 wires)
A2 - goes to A/C pump. (4 wires)

The BEAMS harness A2 plug only has 3 wires. OUCH. time to trace things out. looking at the IM1 connector, it is also missing 1 wire. Easiest solution? I once again pull the missing wire from my old harness. Should be a perfect fit I am thinking. Same connectors, in the same locations on both cars. Ya right. The wire turns out to be about 6 inches short and gets spliced. Wire added.

Well, that's it so far. I hate not having time to work on the car and have decided that Sunday is car day. If I do not set aside time for the car, it will never get done.
