Ls swap coolant temp/oil sensor adaptors

[Marcelo]

Anybody know what coolant temp and oil pressure adpators to run on a 5.3 ls swap? For a 98 4.3.

I wouldn't really run an adapter on the coolant, just pick up a "4 Seasons 37875" for a 98 camaro or firebird. It has three prongs. You can use a TPS sensor plug from a donor, or I think the oil pressure plug also from an LS harness, or something off the 4.3. Connect the two LS pcm wires, and the green from your stock temp gauge.

The oil pressure adapter is "Auto Meter 2268" I don't have the sizes offhand. But if you haven't checked first, make sure you actually need it. Someone had a post recently where they said their stock oil pressure sender was the same threads as the LS, and it turned out mine was also. I think he might have had a 4.3, and mine was off a 97 7.4.

Perhaps a moderator will move this thread to the LSX + Carb Swaps sub-forum.
