Best wiring solution 70 Blazer

[Classic Heartbeat]

I would go with the M&H, and not just because we sell them. I just finnished a complete wiring install on a 72 Blazer and the entire job went smooth as a babie's hiney. Nothng worked on the Blazer when it came in, but now everything works as it should and my customer won't have to worry about the wiring for 40 more years. WES

Gotta agree with Wes, I just did my wiring with M&H, and everything was plug and play. They modified mine to run an HEI and electric choke, all connections were factory ones. The engine harness is about 100.00, but be careful when you take it apart at the firewall/fuseblock connection. You can break it, if you don't take it apart right...

The headlite harness is about 300.00, mine was modified with the high/low beam relays. Here again, everything was plug and play, with factory connections. Quality stuff, and the guys there will answer all your questions. If you go this route, check the locations of the wires between the old and new harness just to be sure that no mistakes were made.

times 3. used M&H in my 67 Chevelle. Hit the key and started right up. NEVER had a problem with the wiring in that car.

I do like the ideas of not having to worry about will it work, my issue comes down to cost, seeing as my build is really a budget build (only being funded by stuff I already own that i sell.) I am really trying to figure out the best bang for my buck.

Obviously the cheapest route is to try and re-use the original harnesses all together. This is attractive cost wise, but increases time to finish. At the same time, if I could re-wire the whole thing, it would be better in the long run as I would not have to worry about anything.

I am currently looking to keep some old and some new as my best option. I would probably be replacing my engine, headlight and tail light harnesses, and keeping the dash harness.

Even with this solution, this brings up another question. The cost of doing just those three will put me near the $350-400 mark. In that same price range is the complete kit from Painless Wiring, which includes the dash stuff.

Just trying to figure out all my options. I have a second hacked up engine and headlight harness, and I believe a second tail light harness as well that I can look into. I also need to dee if my dash harness was hacked up at all still to make sure it can still be used.\

Thanks for all the help so far.

I've used Painless 18 circuit kits and had no problems whatsoever, wires are labeled on the jacket what circuit your working on, quality was not a problem. I'd recommend Painless as well, comes down to a preference thing for me. I've never done an M&H kit but bet their as good as the other guys are saying.

i bought a blazer last february and it had similar problems. all the wires were fried. I had to rewire the whole thing. I went with a kwik wire unit which had everything i needed the whole thing cost me about 250 i think. it took me a couple weeks because i pulled it all out before i rewired it, and i had never wired anything before so i had to learn to solder. Anyways it worked good and was well within my budget. I had a couple questions as well and i called the guy. the owner was the troubleshooter, and he was very nice and new his stuff. i would recomend them. KWIK WIRE. google it i want to say that they are made by st. wire but it has been a while.
