acfortier Posted February 24 Share Posted February 24 I'm planning on creating my own harness to hook up this connector to my MJ: https://www.etrailer.com/Custom-Fit-Vehicle-Wiring/Hopkins/HM40975-11998.html Because the '91-'92 taillight harness connectors are unobtainium, I decided to replace them with a 6-pin Deutsch style connector. The above connector uses 10-14ga wires for the harness, so I got the appropriate Deutsch style for those gauges: https://www.ebay.com/itm/353073619696 However, according to the electrical manual from an '88, it seems the wires in the taillight harness at 18ga. If I cut off the unobtainium connectors and try to splice the 10-14ga Deutsch terminals onto an 18ga wire, I'm not so sure that'll work? My options seem to be: Attempt to crimp the stock 18ga wires into the 10-14ga terminals for the Deutsch style connector Use the 10-14ga Deutsch connector with a pigtail and butt connect (I have solder-seal waterproof connectors) the 10-14ga wires to the 18ga wire of the original harness Use a 18ga Deutsch connector to connect to the original MJ harness and butt connect two 18ga wires with the various 10-14ga wires from the trailer wiring harness. I purchased these style crimp connections to use, which should be able to handle the situation I'm outlining above: https://www.amazon.com/dp/B08XTV93GD?psc=1&ref=ppx_yo2ov_dt_b_product_details This is all assuming that the stock wires in the harness are actually 18ga, according to the electrical manual. If they're even 16ga, I think that gets me close enough to use the 10-14ga Deutsch connectors I purchased. Quote Link to comment Share on other sites More sharing options...
