Hello all and thanks for allowing me to join the forum. I have an issue with my MK3 Supra in that I have a few connectors that seen to have no home. The car has been working okay until I needed to change the cylinder head gasket. Did a strip clean etc. I have 2 connectors that don’t seem to go anywhere. The car has been messed about with but the engine was running although I think the engine harness is not original. I have attached 2 bad photos in the hope that somebody can help. I am now having issues getting the engine to run. It will start and run for a few seconds and cuts out. It’s a 3.0 turbo. Any help appreciated

What transmission do you have? The first pic (on left, more square than rectangle) looks like the ABS connector for the R154. No sure on the other one but may also be a transmission connector - reverse light maybe?
Hello thanks for your reply. The car is a manual but I have a suspicion that it may have an auto harness. I will have a look for R154. Thanks

Oh thank you for your responses I think I might give you an update on the problem I was having. It seems that the connectors go nowhere and at some point in time in the past the harness was replaced swapped from an automatic car. The symptoms I was experiencing was due to vacuum hose is not being collected the car now runs.
