If that’s the same part, for a GT6 and probably a bunch of other applications.

Subject: [TR] TR4 ignition switch


I’m not at all surprised – the ignition switch in my TR4 is not exactly stock.  It might be a TR switch but ?????



Anyone recognize this switch?



I took it out of the mounting today, and individually pulled off the connectors, cleaning what I could and spraying it with an electronic component cleaner.  Anyone seen a tool to clean the inside of those junction clips?  I can clean the tab but how to you clean the female version that is attached to the wires?



Here is what is happening – every now and then the car will get power when you turn the key, and start.  Mostly you get nothing, like a disconnected battery.  No power to anything.  So I’m thinking it’s the switch.  I would prefer to replace it with what ever the heck is in there now.  Note: the original owner had a parts store (FLAPS) and the car is full of non stock stuff, from the alternator to the electric fan, electric fuel pump, 10 fuse European fuse box, etc., etc., etc.  he installed backup lights out of a 65 pontiac, drilling holes in the trunk lid.  Yikes!
