1. Top rear of engine next to distributor

The second option is more likely as it was moved to this location on most vehicles in the early to mid 80s

I have an 87 sierra classic, original engine was 305 TBI,
I have pulled it and replaced w/ pre-1980 4bolt main 350. Truck has a gauge not idiot light. I have the location behind the distributor and I have the one just above the oil filter. I want to remove the plug from the above the oil filter, it is very TIGHT!!! what would be best way to remove this plug? I dont have a torch for heat.
My '87 wiring harness for the gauge is a single tan wire on the driver side that plugs into the single spade clip on the sender above the oil filter. So I need to really remove this plug. I just dont want to break it off. I sprayed lubricant, hopefully it will loosen up.
