2002 Sequoia electrical gremlins! Fixed! (1 Viewer)

[CRSHR]

I purchased this truck with a blown head gasket. The PO drove it without coolant for an impressive amount of time. Got to say these 2UZ are tough engines. I found an engine from a 2003 Tundra and swapped it in. Before I put the engine in it would start up and run poorly but other than that it was normal. Now after putting an engine in I have no speedometer, 4x4/center diff lock lights flash and it won’t start unless I ground/jumper the starter relay. I have been over and over the grounds and fuses. I made sure everything is hooked up just the way it was. Anyone run into this before? Any thoughts? Thanks!

did you use the tundra wire harness or your old sequoia engine harness , they are different

I used the sequoia harnes. Ended up being an in-line connector behind the dash. It was plugged in but I didn’t push the lock down all the way. Thanks for the reply
