Gary Lewis Posted April 19, 2020 Share Posted April 19, 2020 On that note what years work with an 81 truck? Dave ---- Well, that's a very good question. And the answer is, I don't know. But all Bullnose speed control C305A harnii can be made to work. The issue is the position of the power feed to the speed control amp. It changed somewhere between 1982 and 1985 as I'm using an '82 speed control harness in Big Blue and found the change. It is discussed in detail in this thread and following. But that can easily be fixed by removing the red retainer from C305A and swapping pins. Ok got it, so need to check the pin outs between the truck & the CC plugs to make sure they match up. Thanks Dave ---- Yep. Just compare wire colors. Link to comment Share on other sites More sharing options...
Littlebeefy Posted October 8, 2020 Author Share Posted October 8, 2020 UPDATE So this happened: Momo adapter came apart while attached to the column and tore apart the turn signal switch. Looks like the glue failed. Kinda flimsy, I guess. Only the second time I’ve ever bought a Momo part. Bummer. Switching over to a NRG hub. Will post pictures after I rewire everything.
