Re: F/S: 73-87 power window relay harness
 

I PM'd you earlier about the details of the express down option. Let me know if you prefer a splice kit (using your stock window wiring) or if your rather have a full replacement door harness for both sides with or without express down.

Re: F/S: 73-87 power window relay harness
 

Thanks Gmachinz,
Money sent.
I actually just need the upgrade with the relays and express down feature which your quote indicates. I just rebuilt my doors with all new motors clean/greased tracks, and new switches. I look forward to having my windows roll up and down quicker.

Re: F/S: 73-87 power window relay harness
 

Ok...payment received-I'll PM ya when your harness ships-thank you sir!

Re: F/S: 73-87 power window relay harness
 

hi gmachinz. i may have to get with you on the connectors. tried putting awhile back after you sent both door harnesses. then i ordered the center piece. didnt match up. you did send a small bag with other connectors but dont think they matched. been working 75hr/wks lately. but will have a 3 day wkend finally to really look at it. you may hear from me if i cant figure it out an ill get some pix

Re: F/S: 73-87 power window relay harness
 

Ok....you can call or text. There are at least 4 variations on 1981-up trucks with the styles of connectors GM used to mate the LH and RH harness sections to the center. So, I pick the most common and send out optional connectors and terminals-but, if you have something different, shoot some pics my way as I do stock all of them but there's always the chance of an oddball pack con connector housing that could have been used.

And with many years gone by with people swapping doors, modding their own wiring, etc. who knows sometimes. The best bet is to buy all 3 harness sections at once since I use weather pack stuff on NEW 3-harness sets but then, the cost is a bit higher too. Anyway, let me know what you need!

Re: F/S: 73-87 power window relay harness
 

I have options for integrating the older style (Pre 1978) stainless window switches for 1978-up factory power window equipped trucks if anybody is interested. I have come up with a replacement harness just for this swap-its not something you can side into your existing-you must replace your entire power window wiring to do this. Kit price for a standard cab truck is $309.99 or $389.99 if you want express down. If you want to add the power lock circuit to it add another $109. PM with questions! This allows you to go with stainless switches vs. the plastic stockers....doubtful you will ever find a replacement window harness with this type of integration anywhere else!

Re: F/S: 73-87 power window relay harness
 

I'm building a few complete 1984-87 standard cab pickup and 84-91 Blazer power window/lock harnesses today....if anybody is interested in one let me know-this replaces your entire harness or can be used to add power windows/locks to your truck and appear factory. It will work on 78-83 trucks as well but you'll need to source a BAT and switched IGN lead...and you'll need to use an 84-up style power lock relay.

Upgrades over an OEM style harness are:

1.) All terminations are dip soldered.
2.) Heavier gauge wire with GXL crosslink jacketing
3.) Abrasion sleeving protecting harness through the critical door jamb boot area.

$309 is the cost for all 3 harnesses-PM with questions or additional integrated options if desired such as express down and/or up power windows.

Re: F/S: 73-87 power window relay harness
 

Here is one harness set ready to ship-I have 3 more complete window/lock harnesses ready to go if anybody is interested! This is for 1984-up but will work on 81-83 as well. PM for details!

Re: F/S: 73-87 power window relay harness

Re: F/S: 73-87 power window relay harness
 

Cool! Glad you finally found some time to get it all installed! Speed of the window looks pretty good. Did you get everything in the tracks greased/lubed?

Re: F/S: 73-87 power window relay harness
 

No. That a new motor from my other door. I plan on greasing the tracks when i replace all the rubber on the doors an channels

Re: F/S: 73-87 power window relay harness
 

Nice. I'm telling ya....once you get used to having express down and/or up in your truck, you'll want it in every one!

Re: F/S: 73-87 power window relay harness
 

Yup im loving. Can you message me a email an #. I showed some guys on my fb who like to get in touch with you

Re: F/S: 73-87 power window relay harness
 

PM sent!

Re: F/S: 73-87 power window relay harness
 

I'm interested in a 4 door kit w/express down upgrade for my '85 Suburban

Re: F/S: 73-87 power window relay harness
 

Ok....I'll send you a PM!

Re: F/S: 73-87 power window relay harness
 

Adam....I forgot to ask if also wanted express down and/or up for the rear gate glass....assuming you don't have barn doors anyway. I can do all 5 windows as a complete replacement stock window/lock harness or with any combination of express down/up features. I could even supply you with an additional stock type switch to act as an override for all windows at once-express down or up. Let me know what you think-it would require a little bit more involved harness on the power side to be able to handle all those possible options-you'd want to run a dedicated power supply run and side-step the OEM 30A circuit breaker. But, I have a harness addition just for that purpose.

Re: F/S: 73-87 power window relay harness
 

So did you get the other door kit installed?

Re: F/S: 73-87 power window relay harness
 

Yes. Had to replace one the connectors with one of the ones in bag you sent. So they match up. I actually finished it tonight at work. But i think the motor on the new(used) door is no good. When the auto parts open im going to buy a new motor. I scraped the other doors sunday an didnt think about saving the passenger motor. Should have it up an running before i go to work tonight

Re: F/S: 73-87 power window relay harness
 

Nice! It seems GM through the years varied a LOT on certain 2, 3 and 4 cavity connectors in their accessory harnesses. Luckily tho, I stock all the various GM connectors so its no big deal for me to toss a few variations along with the related terminals to make it easy to swap on your end of things should the harness have a different type on it!

Re: F/S: 73-87 power window relay harness
 

Do you have any of these left

Re: F/S: 73-87 power window relay harness
 

Yes I do. I'm about a week out on shipping right now-Im trying to catch up from painting/re-assembling my wife's Yukon. I'll PM ya!

Re: F/S: 73-87 power window relay harness
 

Can you please contact Andy Sinclair in NY? He is the one that bought the harness for the 1980 Chevy. I referred you to him. He said he can't get any return phone calls or emails. I am sure he isn't in a giant rush. Since he already paid for it, I think he would appreciate a follow up as would I since he is one of my customers and is asking me about it. He is a good guy and easy going just probably a little worried since the money is out and he can't reach you. I know these harnesses are really involved and can take a lot of time. I will be getting some from you when I get to that point too.

Re: F/S: 73-87 power window relay harness
 

Yep I already emailed him an update earlier this morning. He needed a specific 6.5 diesel engine harness which was a bit tricky but his harnesses are due to ship out tomorrow.

Re: F/S: 73-87 power window relay harness
 

Great! He actually emailed me this morning so it must have been right before he heard from you.
