So for a good time now, the cruise control on my '97 KA has been out of service. Not sure what triggered it, but it worked fine up until about a few months ago. I'm aware of the clutch trigger switch on top of the clutch assembly, but I'm led to believe this isn't the issue.

Here's what I've come to: Whenever I hit the on/off Cruise control switch on my dash, I heard a clicking coming from my ECU kick panel, so today, I finally decided to check it out. (I've got a road trip coming up and cruise control would serve me stupendously) There's two relays behind my ECU, and these are what's clicking. I know one of them goes to the fuel pump, but when I took the other relay off, the clicking stopped. So I know it's something to do with this relay, whether the wiring or the relay itself. I don't have the best background in electrical work, so could someone explain this so kindly?

What is this relay for/to? It's the one with the black, green and pink wires. Does the clicking necessarily mean a short or a bad ground? If so, and assuming there's someone out there who knows where these wires go, what's the best way to triangulate the source of the problem?

(if it's worth noting, my tachometer busted around the time of this happening. Seems to have a mind of its own, jumping all over like it's possessed...)

Thanks in advance!
