Well just yesterday I asked an electrical question and Warren Hall gave me the answer in less time than it took me to ask the question. I've put a 74 2.7 in a 73.5 and am sorting out the rear compartment electrics. Have made a lot of progress but several "loose ends" remain.
Can someone tell me what this is? I think it may be what Haynes calls an rpm sensor I think, and PET seems to call it a ballast resistor. It has two leads soldered in place and I believe was mounted on the aluminum elec panel in the rear compartment, about 5" rearward of the CD unit, but am not sure. Mine was kind of lying in the back of the car, seemingly unconnected. Where do the electric leads go?
Here's another pic of the rear-most part of that rear auxiliary electrical panel. At the lower right is a 6 pin connector (3 shovel connectors in one row, 3 below these.) Anyone know what this is?
Finally there's the five pin relay socket.
One pin of this socket is assoc'd w/alternator & CD box pin B.
Another pin goes to an unused multiconnector pin, apparently for an option.
Another pin goes to D- on voltage regulator.
Another pin goes to a key switched circuit from that goes to starter solenoid.
THis isn't the relay for the rear window heater which can't be seen on the panel. But what is it? I thought it might be related to the WUR but, if it is, why did the car run fine without the relay itself in place?
With this info in hand, I should be able to make another leap forward. Thanks for any help,
