June 2, 20159 yr comment_471071  I believe the sensor near the starter would be for oil pressure, but I suppose it could be for oil temperature (a modification someone made). It's not stock.  He has a ZX P79 head.  Somebody ran the pigtail to connect it to the coolant temp sensor circuit but didn't finish the job.  Compare the image below to post 38.   If he finds a meter and uses it right it should be an easy job to find the bullet connectors to the coolant temp circuit then run some wire to the CHTS.  Can't get much simpler.  On the engine - there should be some letters and numbers molded in to the block beside the driver's (left) side motor mount.  Either N42 or F54.  1978 stock is N42, 80-83 ZX is F54.  They're both good engines. http://www.xenons30.com/Engine.html Link to comment https://www.classiczcars.com/forums/topic/51532-78-air-intake-probs/?&page=5#findComment-471071 Share on other sites More sharing options...
June 2, 20159 yr comment_471102 Ah, a ZX head! OK, that makes sense. The intake seems to be '77/78, judging from the manifold vacuum ports and EGR. EFI is probably '77/78. Yes, wiring in the translocated CTS should be an easy job.

June 2, 20159 yr Author comment_471112 Okay so it seems one of the previous owners changed to a zx head for some reason my block is an n42 Link to comment https://www.classiczcars.com/forums/topic/51532-78-air-intake-probs/?&page=5#findComment-471112 Share on other sites More sharing options...
