I'm actually in the beginning stages of restoring a 1969 chevy C-10 pickup original 327 v8 400 turbo trans and 411 posi rear end. I cant even remember how many of these videos I've watchedlol. But the Brothers are always the best ones. Always helpful information.

I'm halfway through watching this video. I seen a section I thought I would comment on regarding soldering. This may seem obvious to those that have soldered on electrical/electronic equipment but (NEVER) use plumbing solder. I had a friend restoring a 66 Chevelle SS. He commented to me how some wires and connectors he had soldered on a stereo were corroding very badly. He ended up having to throw away the stereo because the corrosion had traveled into the stereo as well as several connectors. Upon discussing this with him I asked him what type of solder he had used. This is when he mentioned the plumbing solder. Plumbing solder is only meant for pipes. Not electrical equipment! The guy I mentioned is a talented guy. Nothing seems impossible for him. But this is one of those things that just got him.

[@BROTHERSTruckPartsTV]

Wow, great advice!

Yes indeed. Cab? Rubber bushings break [or at least dirty up] return connection and a shunt from cab to frame is bare minium. Same for motor & transmission mounts [most vehicles]. Odd note, but for a 50's ride, if you think you find cotton jacketed wire [as some kind of farm fix], its not - that's AF wire. Replace it, because its day has come and gone.

I was in the market for a wiring harness for my 1978 C20 and found this video very useful. I visited Brothers website to check the price and decided to buy, not knowing if they even delivered to the UK. I placed my order on 15th September which was uplifted somewhat by the shipping cost but not unexpected. On the 17th I received a considerable refund, whether it was a sales discount or shipping adjustment is still a mystery to me, but happy days. The goods were received on the 22nd, just 1 week after ordering. Very pleased with my purchase and Brothers response, I will no doubt be doing more business with them and hope they take the time to read these comments for this feedback. Thanks David.

Thanks for the video Dave and Brothers Trucks. Although I have used many of the techniques seen on this video, it's still nice to watch to brush up on my skills. It's nice to know that I can pick up a relatively complete harness for my '68 if I ever need it. Will it work for LS conversions too? At the 8:11 mark, I've noticed that you have an LS motor DBC under the hood. I would like more information like parts used and installation process, plus your version of wiring harness and ECM. I also see that you had kept the OEM dash gauge assembly. I have a 2001 Suburban with the 5.3 LM7 and the 4L60E transmission that I want to use for my '68. My plans are to rework the Suburban 5.3 wiring harness and convert the transmission from a 4wd to 2wd.

[@BROTHERSTruckPartsTV]

Our harness in this video will work with an LS swap just like the truck in this video. We'll see what we can put together regarding the LS conversion and parts used for a future video project

Thank you for putting this video up! I am looking to replace the wiring harness in my 68C10. As far as I know all the critical components work fine. My plan is to do many upgrades to the truck. LS, Vintage Air, Power windows, Upgrade sound, electric fuel pump, more interior lighting, tank to rear, LED lighting, etc. Will I need to use your engine harness or the one with the LS engine, or combination of both? I can't imagine the factory engine harness even coming close to working with an LS, and I cannot see LS harness hooking up to the old truck connectors, etc. Help please! PS I'm happy to buy the stuff I need from you.

[@BROTHERSTruckPartsTV]

This harness work with an LS install just fine. As a matter of fact, the truck shown in the vid has an LS in it. Your specific LS wiring will be different based on what electronics you use to run the ECU, but this harness will work fine.

[@maxmorter503]

I ordered one of the 12 circuit cheapo ones for my 69 c50. It only needt to start run amd have signals maybe but what im curious about is wiring the guages. Theres one air pressure guage you gotta press a button running off that to power tge hydraulic winch amd dump controls

[@BROTHERSTruckPartsTV]

Our "Classic Upgrade" harness takes care of most of that gauge wiring for you, but your truck has something unique that most don't with the hydraulic system. However, the Classic Update harness is plenty flexible to accommodate that system while making the rest of the install much, much simpler.

[@maxmorter503]

[@henrydixon3159]

great video I just finish wiring my truck but having problem with my dash gauges nothing working but the RPM gauge any advise you can give me

[@BROTHERSTruckPartsTV]

Best place to start is with the ground. Attach a separate ground wire to the back of the gauge housing and run it directly to somewhere on the cab and see what happens. If it's not that, then it's likely your 12v power source to those gauges.

[@U_y_g_h_u_r_L_i_v_e_s_Matter]

[@TempoDrift1480]

I hope these have heavier wire than that Christmas light shit GM uses. I can't tell you how many cars I had to completely redo with #12 THHN. The factory wire was so thin, just stripping the insulation broke the conductors just about every time. Also, is this the same harness I need for an 85 Suburban?

[@BROTHERSTruckPartsTV]

This would be the harness we suggest for your 85 Sub. Wires in this harness are typically sized and suited for their intended use. Whether that's the same as GM, in some circuits yes, but in most they have been updated to handle a more modern application.

[@johnbergeron849]

I am trying to figure out which harness I should buy. I have a 66 C-10. I am adding an A/C to it and that is about it. I dont know if I should get the 13 circuit or the 20 circuit

[@BROTHERSTruckPartsTV]

The 20 Circuit is the most common harness we sell, and we recommend it over the 13. It's just always better to have the option to expand instead of cutting into the harness later for something.

[@raphaelina70]

You do explain things very clearly, but I doubt I could replace the gauge myself. I'll have to take it to an auto repair person, but it would be helpful if I had some idea as to what's causing the problem with my 2005 Chevy Malibu gasoline gauge. The indicator needle vacillates between full and empty (usually goes to empty when I stop at a red light). Can you give me some idea as to what would cause this problem?

[@BROTHERSTruckPartsTV]

It sounds like a failing sending unit, but it could also be an intermittent dead short on the sending unit wire that only shorts when you are braking.
