Michael Rice Posted December 11, 2021 Share Posted December 11, 2021 Without having to pay an acupuncturist again next week, is there a quick link to the color / function of the wires going into the back of the fuse block for a '89 MJ. I'm replacing the original fuse block with an aftermarket one. Thanks in advance. Link to comment Share on other sites More sharing options...

boxyjeep Posted December 12, 2021 Share Posted December 12, 2021 Unbolt the existing fuse block, unplug it from the engine side. Put them side by side on the drivers floor and remove each pin one-by-one to replace. Also, why did you buy a replacement? Were your pins shot (these can be replaced--parts on Del City), or was the fuse block itself plastic melted? Link to comment Share on other sites More sharing options...
Michael Rice Posted December 13, 2021 Author Share Posted December 13, 2021 Thanks. Not as simple as it seems as the pins don't remove easily. The new unit does not require the pins. The original is melted in places, and needs replaced. Microsoft Word - 30003.doc (painlessperformance.com) Link to comment Share on other sites More sharing options...

Microsoft Word - 30003.doc (painlessperformance.com) It can be done with small screwdrivers on each side, there is however a tool to make it easier. Shove the green one of these down in there on each side of the terminal https://amzn.to/3DMFrhh I recommend replacing the connectors while you're at it because they're likely brittle by now. 1 hour ago, oleskool said: Link to get new pins.
