Willie dog Posted November 25, 2015 Share Posted November 25, 2015 Has anyone out there ever used the wiring harness from watts? I am looking at getting it for my 60 b 42 model. How complete is it? Is it a decent harness? For $1800 it ought to be a good one. Quote Link to comment https://www.bigmacktrucks.com/topic/42825-watts-wiring/ Share on other sites More sharing options...
68-f-model Posted November 25, 2015 Share Posted November 25, 2015 For $1800 it better install itself . I put a modern blade type fuse block and full harness in for about $175 .

Popular Post 41chevy Posted November 25, 2015 Popular Post Share Posted November 25, 2015 I bought one from Barry. It is exactly what was installed at the factory, OEM style connectors, wire loom cover, color coded cloth over modern insulated wire. But that said if you aren't going for a show restoration, make your own or go Painless. I bought it or my Mixer because I want the factory look. Paid less than 18 from Watts last year too.

Willie dog Posted November 25, 2015 Author Share Posted November 25, 2015 Thanks to all. I'd like to go with something that looks original. I would like to have the correct cloth cover and correct terminals. I've installed Painless harnesses in several projects and for the price you can't beat them.

AZB755V8 Posted November 25, 2015 Share Posted November 25, 2015 Did my several years ago. Go to the Mack museum site and look at the list of vendors. There is one that does original wiring with the cloth covered wire as used originally. I don't know if it is as pricey as Watt's but it is probably were Barry gets his anyway. Take a minute and look it can only save your money. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/42825-watts-wiring/#findComment-312982 Share on other sites More sharing options...
Popular Post kscarbel2 Posted November 26, 2015 Popular Post Share Posted November 26, 2015 Mack Trucks for many years purchased its wiring harnesses from Dill Products in Norristown, Pennsylvania.Dill Products evolved into Fargo Assembly of PA, still operating in Norristown to the present day.The B-model main cab wiring harness (part number 41MR439) used to be around $300. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/42825-watts-wiring/#findComment-312988 Share on other sites More sharing options...

That harness was extra.Harnesses Unlimited. Wiring Harnesses made. PO Box 435 Wayne, PA 19087-0435 Telephone: 610-688-3998 is probably the one Watts uses. They custom make them to order. 2 Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/42825-watts-wiring/#findComment-313013 Share on other sites More sharing options...

Hi I am new to old Mack’s currently trying to resurrect a 1987 mh600/613 cab over with my dad with a wiring nightmare we have been replacing single wires and got as far as we can start it from the junction box for lack of better terms but can’t get any power to the cab at all or the ignition how did you replace the harness for under $200? Also how do you know what wire goes to what as they are not really color coated? And and all help or tips would be really appreciated thanks in advance D.

hurstscrambler Posted March 22, 2020 Share Posted March 22, 2020 Well, these fellas were talking about earlier trucks that have much less complicated wiring than your 87 would have. There are many companies that make universal type harness for hot rods and whatnot, personally I have used Painless performance, American Autowire, and Ron Francis kits. I was happy with all of the although the American Autowire seemed to be the best bang for your buck. Summit racing or Jegs are a good place to buy things like this, just find a kit that best suits your needs. Finding the proper terminals to fit your factoy connectors is likely going to be the largest challenge. Hopefully someone can chime in and get you a wiring diagram for your truck. Is the harness really in awful shape or are you just having a hard time troubleshooting? Electrical issues can be very annoying. Good luck.

Dee. Posted March 22, 2020 Share Posted March 22, 2020 Ok thank you and the harness is pretty bad where it runs under the floor and above the steer tire lots of broken rotten wires so it’s difficult to be sure where some even went and I also can’t get the harness un hooked to reconnect a couple that broke up tight to the connection Quote Link to comment https://www.bigmacktrucks.com/topic/42825-watts-wiring/#findComment-446347 Share on other sites More sharing options...
Rob Posted March 22, 2020 Share Posted March 22, 2020 I've always hacked a block out of a later model automobile and sourced the electrical terminations from automotive suppliers such as "Auveco", or "Lawson Products" which now sell online. Get the correct removal, and crimper tools for their terminations also as it takes a lot of the tedious work out of building harnesses. With broken wires there is no substitute for a good point to point schematic and they can be obtained, or modified from an existing print. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

68-f-model Posted March 25, 2020 Share Posted March 25, 2020 Agreed a 1968 is considerably less wires than a 1987. I ran a main power to the fuse/relay block and then replaced one old circuit at a time. Have patience and best of luck with the repairs.
