About to put a Painless harness in my 84. Have any of you fellas done one of these? If so, do you have any advice before I get started?

I'm helping a buddy do one on his 72 bronco before I do mine. As I assumed his would be easier, it doesn't have all the extras my Silverado does. So it's pretty well figured out.

Just thought I'd check in and see if I was over looking something that might help things along. I've got a diy4x dash with a bunch of gauges I haven't hooked up yet because I've been waiting to do this harness so I didn't have to chase wires twice.

(For years I've bought parts for my K5, but worked too much to have time to put them on. One benefit to being unemployed is I'm finally getting around to it)
 
My only advice will be to wire up the instrumentation on a sub harness so that it can be disconnected as a whole should you ever need to remove it. The painless harnesses are all marked wires as to what they go to and aren't too tough to lay out. Painless has a book they sell on "How to wire your Hot Rod", it will cover just about any project though. http://www.amazon.com/How-Wire-Your-Hot-Basics/dp/1929133308 They used my 1931 Ford Roadster as the vehicle for the book, it is on the cover, my 15 minutes of fame :rolleyes:
 
Did one in my 67 Firebird. Most of it wasn't too difficult. I laid out the harness on the floor and set it up to get a good overall as to where everything was supposed to go. I then paid really close attention to how the factory ran theirs and tried to emulate that. My kit didn't come w/ many of the connector ends - bought the car and it had the kit w/ it so it may have been universal... Just be careful of how you run it, no pinch points, or places to rub the insulation off. And since cellphones w/ cameras are in everyone's pocket today, take lots of pics when you take things out. As reference. Have a factory wiring manual handy for reference also.
 
Thanks guys. I bet I would've spaced the detachable gauge cluster. I did on that bronco, even though I'd mentioned it before we started that project.
 
So I was doing fine until I got to the neutral safety switch. But I haven't had one since I went to a floor shifter a few years back anyway. Now I'm looking at the power windows and locks. Painless gives me one hot for each, so I'm guessing I just find the power and tie in there?
 
I have to tie the two yellows into these for my power window and locks. Do I just tie into power and forget the rest?

How about this one. Does anyone have an idea where I can wire in my Street Fire ignition? If I go to the fuse block accessory port the only way to shut the blazer off is to pull the wire out.
 
Did you get any extra circuits? If not you'll have to pull from the ignition circuit or put an accessory fuse block in.

Seems like everything on the fuse block is B+. It's the chevy harness on painless for a 84 full size truck
 
Just looked on their site and there's a circuit for an electric choke, if you're not using that, or the fan circuit if you're not using electric fans.

I'll definitely give that fan circuit a go. But I think it might need a switch though. I was thinking about finding a ignition hot on the column. And the same for the dash lights on the headlight switch.

I'm trying to get her good to go for a move out to cali. You know your serious about your blazer when you are selling your 06' Malibu to drive your 9mpg K5 900 mi. (To be with the kids, and a good paying job)
 
Then I'll just have the wipers to do. They supply like 8 wires and the stock hook up is just 4.ugh
 
I found a key positive accessory port on the fuse box but it's not enough to crank my streetfire ignition box?
 
Voltage shouldn't be low, if it is there's resistance someplace. If it's trying to pull too much amperage you'd pop a fuse.
 
Only things I don't have done is the rear window, and that should be simple(painless didn't even have anything in the harness for that), and the wiper switch. They give like 8 wires to plug into 4. WTF,right?
