    Hey guys, been a form reader for awhile, this my first actual post.. need help.. I have a 91 4.3 vin code z with about 420k. I've done a bunch of work to it. I'm on to the sending units. I've got a single wire sensor between 2 and 4 I'm assuming that's a temp sender. I have a long oil gauge sender by the distributor. There's a gauge hole between 3-5 not being used. And then I hav 2 more senders on the back of my block under the big oil gauge. What are those for? Oil light? Oil temp? Knock? I'm supposed to have a coolant temp by the therm housing but i don't
