Same kinda plug as in the O2 wiring harness. It has a snapon piece/cap that looks like 2 wires should be comming out. Take the cap off and there is only one prong. I bet it's along the firewall, probaby where the main harness comes thru the firewall.
Thanks - I looked around on the firewall but perhaps I missed it - I'll look this evening again if I can get out there. If someone knows - please chime in. And thanks Dave for looking if nobody else chimes in.
One thing I did notice was that during the advance stage during warmup, as the engine got warm (nearly ready to idle down), the rpm's were going up and down (cycling). I had the timing light on it at that time and it was cycling between 20 and 5 BTDC. I'm thinking that was because, at that time, the timing was at 15* BTDC, but I don't know. I'll pay attention next time it's warming up and see if it cycles again. Especially after I find the plug to ground and get the timing right again.
Incidentally, does anyone have a source for the idlers for the serp belt? I thought I had a solution, as there were two on a Montero at the local yard, but they were both dry too. I thought I might be able to pry a seal off (I've done that in the past on Toyotas) and repack, but I can't figure out how to get into these. The bearings are good, for now, but they are dry and making quite a bit of noise. Any suggestions?
