My GP relay won't engage when hooked to either, but the gauge in the car works when hooked to either. When I leave the blue/white to the sender disengaged, the relay works properly.
Both AutohausAZ and GAP list both senders as being the same. What gives? Anyone have a part #?
For now I'll just leave it unplugged, but I do want it fixed for the warmer weather.

Actually, if I leave the blue/white disconnected, will the relay & GPs keep energizing when the engine is at operating temperature?
Yes there are two identical *two* temp senders... one for the dash gauge and one for the glow plug relay.
The fact that your dash gauge works with either suggests the senders are ok... pointing a finger at the glow plug relay. It's programmed to come on for 20-30 seconds when very cold *or* if the sensor is disconnected.

But as stated, the relay works properly when the blue/white wire is disconnected, just as the Bentley says it should. I did count to about 20, then heard/felt it un-click.
Your write-up did answer the 2nd question, though. Once the starter is engaged, the relay/GPs will shut off.

Yup, that's how it's supposed to work if it can't see the sensor.
However, it sounds like it's having trouble actually *reading* the sensor.
OK, I kinda get what you're saying, now.
I'll try cleaning the contacts, then run a jumper wire to see if that's the issue before I buy another relay. I think I have a spare, but it would probably take longer to look/find it, than order one and have it delivered.
Thanks!

I finally got around to trouble shooting this. Replaced the terminal, then checked continuity... everything reads good. Guess I'll be getting a new relay.
