So I started a thread "Bet u havent seen this b4" where my speed sensor shorted and burned up/melted and the speedometer stopped working, obviously.
http://www.3si.org/forum/f35/bet-u-havent-seen-b4-657722/
Since then, I have received a replacement pigtail connector that I soldered into the engine wire harness hooking the wires up correctly to the existing wire color code. (yellow, black, black w/white) and have now tried two separate used speed senors. However, the speedometer is still not working... no cruise or active aero either. Everything else works, fuse 11 is good.
I have tested for positive and ground at the pigtail connector and are getting both, but not from the wires I was told by escape-performance going by the wiring diagram he was using.
Fact- my positive wire is solid black and ground wire is black w/white stripe, yellow is of course the wire going to the ecu. His diagram said the opposite though- solid black is ground, black w/white is positive... but that's not the case with my 1991.
At any point did Mitsubishi switch/change the engine wire harness section going to the speed sensor so that the sensor's ground wire was solid black and positive was black w/white? I can tell that the pigtail is from a newer year as my "yellow" wire is more of a dingie yellowish clearish looking rubber, but the wire coming out of the pigtail is a nice solid yellow.
Hopefully tonight I will have the time to send 12v to the yellow wire at the pigtail, and using a test light at the ecu connection confirm that the yellow wire is still good all the way to the ecu. If it is still good as I think it will be, then what else could my problem be? The bottom gear section still seems to be fine as the pin won't turn, but I haven't pulled it out to confirm 100%.
Could the ecu have gotten screwed up when the sensor fried? (eveything else works and car still runs great though?!) Or is it just bad luck with the used sensors both being bad? Escape-performance sent me another used replacement already at his expense but it's still a no go as well. I'm positive it's not the gauge cluster because cruise isn't working so it's surely sensor, connection or ecu related.
Any input is greatly appreciated!!
