Don't even take his DME out from under the seat! Simply unplug the large cable from the DME in his car leaving his DME bolted down as is. Then just plug the cable into your DME and place it safely in front of the existing DME or on a towel ontop of his existing DME. Your DME does not need to be bolted down to test it in his car, just plug it in and take for a drive. Will take no more than 2 minutes to get it plugged in. If you like also bring your DME relay along and test that also in his car, first just your DME then if all is well put in your relay and test with both your relay and the DME together.
Any 84-89 DME will work in any 84-89 car. Sure some DMEs are diffrent over the years but the engine and wiring is the same. You can put a 84 DME in a 89 car or visa-versa.
The Jumper you are talking about was most likely so that his 84 2K DME could run a 24pin 4K chip instead of a 24pin 2K chip, very common upgrade. Another common upgrade I do all the time is upgrade DMEs to the latest 88-89 8K 28pin chip. But having these upgrades does stop a DME from working in any 84-89 car.

Ok perfect, thanks Sal, we will try that. my DME relay is new, it should not be an issue. I was swapping between the old and the new and there was no difference. I will also unplug the O2 sensor. I had unplugged it when I started trying to diagnose if it was culprit although I had not noticed any changes.
I will also put the black coil back and keep the silver one as a spare.
I have a picture of my DME although it is not HD nor is it a close up... It's only of the outside/top side. I can't say that I really enjoy playing around in there.
Thanks,
Mark
