Thread: Cruise Control Module Pin Out

Hello everyone, I'm new here and hoping someone can help me out.

After a couple years of sitting in storage, I have discovered that a family of rodents have decided to move into my engine bay. Apparently they have survived by eating wire, chewing completely through a handful of wires near the cruise control module. I have been able to fix everything by splicing and soldering in new pieces of wire... BUT I hit a snag. The Cruise Control module's 10 pin plug has 2 identical green wires, pins H and K (which they say right on the plug) I've scoured the internet for a diagram or schematic that could tell me where the two go... but found nothing.

If there is anyone out there with a multi-meter that could simply unplug their cruise control module and test resistance or continuity to ground or to the other pins, anything to distinguish H and K apart, I would really appreciate it. That's all I'm waiting on to finish this job and guessing makes me nervous. Otherwise, if any techs out there can confirm that it's safe to hook them up backwards, I can figure this out by trial and error.

The car is a 97 3.8 SC

Please Help!

I can say that one of them (H or K) has a resistance of 65k ohms to pin J (located between H and K).
I am doing this with the battery disconnected, but I don't think that would would make a difference.

The difference between H and K on the paper is the wire going to K also goes to the BCM too while the wire to H doesn't.

Great info! Thanks!!

Unfortunately, both green wires show continuity to green wires in the BCM. Any chance you could share that schematic? Or the pin # for the K wire @ the BCM?

My bad, I was testing at the PCM not the BCM. Only 1 wire shows continuity at BCM, it's pin #15. Thanks a ton iefalcon!!

You got it. It's 15 in BCM. It also goes to HUD, dash..., where the speed is shown.
