What wiring harness to use?

[72truckman]

I need a full replacement as my stock one is thrashed.... Ive heard good and bad things about PAINLESS... What have you used?

[Critter]

Are you going to try to splice an aftermarket 67-72 harness into a factory 5.3 harness? Or are you looking for something that will take care of everything including your engine swap? I don't really have an answer, but the extra detail might help someone else jump in.

[72truckman]

I already have the engine wiring harness down to a 4 wire plug and play... Im talking about a full headlight to taillight harness such as http://www.jegs.com/i/Painless/764/10206/10002/-1

[KevsClassics]

I recomend the EZ wiring 18 circuit universal harness. For half the price of a Painless. It does not use a bulk head connector thru the firewall you can weld that hole and you can hide all your wiring for a clean look. I have done this many times before with great results.

[72truckman]

That ez harness looks great! i thought that $400 was ridiculous for a harness... ive never wired a truck before, do you just cut off the stock wires at the connectors and splice into the new harness or???

I like the M and H but the catalog sucks IMO. I can't find what I want (it's just taking forever to find it and i'm impatient), I guess it's better to just contact them and tell them what you're looking for.

AAW is coming out with their Classic update kit for our trucks in Dec. They have the mule in their shop now.
Thats what Im waiting for.

What he said. They can also customize it for any changes or mods you have made.

I don't know about the other manufacturers, but in my opinion Painless is a cheep wiring job. Put together with butt connectors. I prefer to make my own starting with a decent factory harness, and using factory style connectors, and solder and shrink wrap. I have found butt connectors create problems in time, and have to fix many Hot Rods with wiring problems do to high resistance from bad contacts.


Heres one that drove me batty trying to find wiring problems

On the dash harness it is listed with guages and without guages? How do you tell which one is which?

[vanislejimmy]

I couldn't find a kit for blazers on the american auto wire site. Do you know the part number or did you use a fullsize truck harness and shorten the tail light wires

[tallhoedude]

i found a painless 18 ckt harness on ebay about 1.5 yrs ago,paid $200.00
and it was nice.easy to install,all new connectors,new style fuse block,plenty of length of wire...would buy painless again for sure.
plus it was very easy to hook my 5.3 harness up to as well.
just my .02

AAW list the blazer and suburban specific stuff under full size truck.

[bigbadchev72]

i got a summit racing 18ckt one in my blazer, easy to install and was only $200

[65-72 chevytoys]

When ordering the under dash harness from any of the manufactures it list instruments with guages or without guages?? Anyone know how to identify which is in my truck? Does that mean the idiot lights? or something else?

[6768chevylover]

its for the trucks. trucks blazer its all the same.. wires are long enough for the blazer as well..

[superlifted]

Get a painless. It cost more but it's worth it. I hate my ez wire.

[JNSM653]

Did a painless last summer in my 69 K5 and I'll say it may seem expensive but in the long long run worth every penny, I say that because a bought an AAW for my jeep and I can say that the AAW kit is not as complete as the painless and the diagrams aren't as good either. To each his own in the end though.

Curious if this is the Painless wiring harness people have used? Is $520 worth it?

I have soo many crossed up wires, bare hanging wires, loose ends under my dash I feel like I need to take control of this mess. Plus my fuse box is pretty much rusted over.
