What brand of wiring harness?
What is everyone's opinion of the different harness brands? I'm planning on re-doing every inch of wire, so if you've got experience with the different types, please give me all the pros and cons of each.
Thanks. Ronnie

Re: What brand of wiring harness?
i used the painless one for my build. it took me about a week to finish but that could be because im ony 17 and still in school.
pros: every wire is labled every 16 inches of so, it is already zip tyed in to the different sections it comes with an 18 curcit push in fuse box all plugs are already connected good instructions cons : it comes with a maxi fuse for if using a one wire altornator whitch and be confusing the price ![]() all and all i am very happy with the product PM me with any other questions

Re: What brand of wiring harness?
If you are going back stock, American Auto Wire is hard to beat. Their harnesses are even correctly color coded as well. No negatives with AAW.

Re: What brand of wiring harness?
We carry the M&H wiring harnesses and they are 100% exactly like factory in appearance, only difference is wire insulation & plastic connectors are made using the latest technology so there made better to resists the elements better than original harnesses.

Re: What brand of wiring harness?
hey Paul,
does M&H offer an aftermarket solution like Painless? I'm interested in upgrading my wiring to something more modern with leads for my electric fuel pump and sending unit near the back bumper, amongst other things. I'm curious if I'm stuck using Painless on this one.

Re: What brand of wiring harness?
Since the M&H harnesses are factory original you do not have additional fuse locations to add additional circuits. You can always use the 1/2 dozen spade terminals located on the stock style fuse blocks to protect some new circuits & HIGH AMPERAGE draw components such as Amps should be wired direct to the junction block on passenger fender with a heavy grade in-line fuse or circuit breaker.
But if you need more than that a painless wire harness would be the solution. GMCPaul |

Re: What brand of wiring harness?
Hey Paul,
Do you have a part number handy for an entire harness? It's a '68 BB 396 with HEI and AC. Let me know what other info you need.

Re: What brand of wiring harness?
rophle1 Because of all the variables on each truck we don't have kits made to do the entire truck as some may want new radio power wires, heater harness w/o A/C and a fuel sending wire in his kit and the next guy wants none of those 3 but instead wants the under dash courtesy light harness with light, best thing I can say is email me with a list of which harnesses you want or just start on this page of our web site adding the the specific harnesses you need
http://www.gmcpauls.com/Electrical.htm then each of the following pages http://www.gmcpauls.com/wiring_harnesses.htm http://www.gmcpauls.com/wireharness2.htm http://www.gmcpauls.com/wire_harness_3.htm until you have all you want for your truck. |

Re: What brand of wiring harness?
A couple of weeks ago, someone put a link up for an EZ wiring harness on ebay that fit our trucks. Does anyone still have that link?

Re: What brand of wiring harness?
I've used M&H with all 4 of my chevies and have not had a single issue with them. The come with all the connectors on them (headlights, side marker holders, etc...). They can be custom ordered with HEI options and alternators on the passenger side and so forth, but still use the original fuse box (as stated above) and that puts some limits on them.
I have a friend that has used the painless kit in both of his cars and swears by it. |

Re: What brand of wiring harness?
I don;t like Painless because of how incomplete they are and you have a mess of wires bundled under the panel for all the extra circuits you did not use. I really hope AAW comes out with a retro harness soon, but they are one of the most complete aftermarket harnesses available. They have them already for all the earlier Chevy trucks now. You could use AAW's Street Rod Highway series harness which is stupidly simple to install, no extra wires, and comes with ignition switch, headlight switch and dimmer switch and most of the connectors. Available in either a 22 circuit or 15 circuit.

Re: What brand of wiring harness?
Hey Mike,
What kind of wiring harness from AAW would you recommend for a guy like me who has: - '68 pickup - Added an LS1 out of an '01 TA WS6 - Using the factory LS1 harness (hacked - only requires tying into purple IGN lead on stock '68 harness) - Using the factory '68 harness for horn, lights, blinkers, trailer, dash lights, fuel sender, radio - factory 12v regulator is deleted - A/C is deleted, so is the air/heat box under the dash - Have dual electric fans (requires 2 relays + power + fuse) - Electric fuel pump (requires 1 relay + power + fuse) - Uses single-wire alternator - Adding power windows later - Adding power door locks later - Using aftermarket Flaming River column - Eventually using aftermarket gauges - I have the towing/trailering lights package intact - Radio and cig lighter are intact Just curious what options are available. I am happy with the look and feel of the Painless kit I worked with on another board member's truck, but there were a lot of add'l wires I didn't need, I thought the one-wire alternator "master fuse" crap was a joke, and the fitment of the bulkhead to the firewall was craptastic at best - looked sloppy as hell IMHO -- but the flexibility of the Painless kits is nice, fuel pump leads, power window and door leads, etc.

Re: What brand of wiring harness?
Hi Mike - I would like to have all my wires/electrical system upgraded in my 70 K5 Blazer. Would the Highway 22 work for my vehicle? I probably will not ever put in power locks and windows, but will be putting in amps/stereo components, bigger alternator/extra battery, etc and having the option to always add it on later is a nice option.
Is this the best fit for me or is the Highway 15 or something completely different a better option? I have no clue about this, but would like to have my entire electrical system upgraded to todays standard. Is there any other wiring kits needed in addition to these systems or does this completely cover all electrical needs for a vehicle? Thanks so much for any help on this. ![]() |

Re: What brand of wiring harness?
I saw that at their site - do you have a close-up shot of that box? I want to see what you mean by "no wires showing", it looks like you slide the wires into the bottom and tighten them down, and I'm not sure how that would actually look installed in the truck.
Do you know anyone who has installed one of those into our trucks? Curious how much trimming is involved, and what the fitment is like. Pics would be great (you got a sale riding on it ![]()

Re: What brand of wiring harness?
rophle1: With all of the hijacking above aside, I have a Painless 18 circuit harness and am very happy with it. At the time I bought it mine, I wasn't a board member and Painless was the only one I knew of. Although Painless is a damn good product, in retrospect I think I would have gone with the AAW harness mainly because you won't have the extra unused wires until you need them. Just my opinion.
