Hey everyone! New guy to the forum..Just picked up a 1968 Chevelle..factory 307 car but has a 327 now..Not sure what it came out of..First issue is temp gauge is inop. The sensor I believe is on the pass side head (which is the opposite side that everyone said it would be in) Is it a safe place to start by just putting an aftermarket temp sensor in? One wire comes off of the sensor and runs to a wire cluster on the firewall..No breaks or shorts...Anything helps, Thanks everyone!
