I have this plug that goes into the back of the block and the end was cut-off, so I have no idea where it hooks up. It plugs into the block between cylinder 2+3 about 2-3 inches from the deck. I didn't see any cut wires in the harness , but I didn't look too hard yet. Can anyone tell me what this is and where it hooks up?

Second, I think the machine shop mixed up my cam gears when they polished my cams. I just wanted to make sure. I put the exhaust cam(i thought)in and placed the keeper on the end. Then, I put in the intake cam in and when I went to put on the keeper it wouldn't fit in the slot! I noticed that the intake keeper was wider than the exhaust cam keeper, is this correct? I took out the exhaust cam and looked at the part number( first section=444second section-50742-2oposite side=2939)and then the other cam has the exact some part numbers stamped!!! Anyway, the cams have different sized slots for the keepers so I switched the cams and now the keepers fit. Is this correct? They only fit in one way correct, big keeper on intake with bigger slotted cam+smaller keeper on exhaust with smaller slotted cam? Are the part numbers suppose to be the same? Is, there anyway to tell intake/exhaust from part#'s? Sorry for all the questions

Thanks

The exhaust cam gear has the ridge thing around it, to keep the belt in place. Hope that helps.

The intake cam thrust plate is the wider of the two. As for that plug,not a stock plug for a TIII.........

Yes that's for an engine block heater. It plugs into a regular 120V house outlet.

Block heaters were common in cars ordered in northern states/Canada. My Canadian IROC R/T had one on the build sheet.
