Donlock Posted July 19, 2019 Share Posted July 19, 2019 Just wondering if there are any tips on doing it ,car was restored in 1974 still in good condition. Thanks Don Gower Link to comment Share on other sites More sharing options...
stvaughn Posted July 19, 2019 Share Posted July 19, 2019 Do you have a wiring diagram? Are you installing a pre- made kit or building it yourself? I rewired my REO using color coded wiring from Brillman. This allowed me to make some modifications. Added electric fuel pump, turn signals, and added a better fuse panel in a more accessible location. Except for the alternator it looks bone stock.

Old26Buick Posted July 19, 2019 Share Posted July 19, 2019 (edited) I bought my wire from R I wiring. I install a fuse panel(glass fuses) from Napa and mounted way up under dash. I also used a solenoid between battery and headlights that was activated by headlight switch. More direct flow of current and brighter lights Edited July 19, 2019 by Old26Buick (see edit history) Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted July 19, 2019 Share Posted July 19, 2019 1974 should still be good wiring. What are the issues. I would think most of what you have is still good. Hugh Link to comment Share on other sites More sharing options...
Roger Barrett Posted July 19, 2019 Share Posted July 19, 2019 The RI wiring harnesses available new are really nice. It is likely if the car was restored in 1974 the original harness was left alone and is now nearly twice as old as it was then. Who knows how long new harnesses will be available.

Donlock Posted July 19, 2019 Author Share Posted July 19, 2019 I have a new harness on order ,when restored in 1974 the wiring was not to bad, the wire in conduit is probably not bad, but the exposed wire has bare spots. I am thinking remove dash panel would make it easier. Don Link to comment Share on other sites More sharing options...
raydurr Posted July 19, 2019 Share Posted July 19, 2019 The under dash portion can be completed in about an hour with the instrument panel in place. The 90 year old wire has far exceeded what the manufacturer intended . The few hundred dollars to replace the harness will prevent roadside breakdowns as well as greatly reduce the risk of fire.

I agree. The dash wiring is so simple, you could do it in the time it takes to remove the dash. Link to comment Share on other sites More sharing options...
Donlock Posted July 19, 2019 Author Share Posted July 19, 2019 Ok I did that way back in 1968 and I guess I can do it again I am 73 years young. Not as flexible as I use to be. Don G. I was a Locksmith and safe cracker for 40 years and cancer in 2007 and beat it , And now last August I found out I had aggressive cancer and went to my bones. But after the first chemo all the pain went away, so now they are keeping at bay. I feel pretty well and enjoy working on my cars. 3 Link to comment Share on other sites More sharing options...
Mark Shaw Posted July 21, 2019 Share Posted July 21, 2019 I replaced the broken breaker unit with a simple fuse when I did mine.... This is an older photo: Link to comment Share on other sites More sharing options...
