1977 High Sierra ole farm truck

[gmachinz]

Firewall junction with all the added power runs. The sealed fuse holder is a 10ga lead which will feed the electric fan relay bank on the core support as well as the integrated relay upgrade for the headlights.

not sure why image is sideways....lol

[gmachinz]

New dual tank dash harness extending to existing 4-wires.... converted the existing 4 wires from the tanks to a 4-cavity weather pack setup.

[gmachinz]

Under dash is a mess lol but hey gotta do what I gotta do!

[gmachinz]

Just a couple bolts holding the new fender on-I need to route the new front lighting harness and there's some mods for it too-relay power and delay off.

Looking good!

Got a little more done on the 77 this weekend....we had a family bar-b-que and I couldn't stand looking at the truck without doing something while waiting for some food so....

....here's a quick shot of the 81-up style power door lock relay mounted to the left of the accelerator pedal bracket.

[gmachinz]

If you look behind the ebrake bracket you can see where I route the NEW power window/lock/mirror harness just like factory 81-up trucks do.

[gmachinz]

So this pic has a back story....my father in law decided after I had refinished a pair of standard manual door panels for his originally plain jane optioned 77 GMC that he wanted to have power windows and locks after seeing my various express down/up installs on other trucks-so I said fine....I'll build an 81-up style harness for use with your 1977 fuse panel, I'll add a few more circuits and you just need to source nice power doors.....easy right?

Well, he picked up some rust free 1991 Suburban doors and now he wants to add power mirrors! So after already routing the window/lock harness, I needed to add a mirror harness seperate-(usually I integrate all 3 options into a single harness run) but for those of you who may like to add power mirrors to your truck and don't need a new window/lock harness, you can simply drill a 7/8" hole directly above the factory grommet for the window/lock door harness and run the mirror harness out through there and into the door boot.

[gmachinz]

So once it's done it will look something like this...and Indont know why my recent pics are showing up sideways but oh well....

[gmachinz]

Basic door shell layout of my window/lock harness with wiring protected in heat resistant looming-nobody else can offer as high of quality harnesses as what I can provide.

[silverbear]

Nice work. It is funny how much time wiring consumes. You take the time to route it properly and protect it... and then you cover it all up with door and trim panels.

GMachinz, about time for a full-body shot of your truck. Lol!! Seriously!

In the interest of helping, not hi jacking here, I think the question was about using the lens cleaner to remove the yellowing from the bezel. Michelle, you can clean and polish the cluster bezel (and the clear lens itself) by hand and achieve good results. You can probably do a decent job with them in-place with careful masking, but they are so easy to remove with just a few screws. It'll go quicker with better results. And the risk of damaging nearby finishes is removed. Maybe gmachinz will share what products he uses since they obviously work well.

Just a few random front end progress pics....

[gmachinz]

Yeah so several years ago my father in law had a "body guy" put rockers and cab corners on his truck and at the time I thought it was odd this body guy never requested him to bring the doors he planned to use....truck was pretty crusty and after bolting on a set of GM doors for the helluvit this is what we get-yep....I get to cut this **** all off and re-do it myself.

[Dads79GMC]

Besides that, looking good gmachinz!!

That's exactly the reason why we hate relying on anyone anymore, what a PITA having to redo someone's crap work.
