Manual to Electric Tailgate Wiring?

870 Views 6 Replies 1 Participant Last post by  gregmgm
I'm replacing my rotten tailgate on my '76 Blazer. The new tailgate is electric and my old one was manual. Having never been known for my wiring, I was hoping some of you could walk me through it? I am not sure where to wire it up to on the fuse box. I did fugure out how to raise and lower it with a battery, so I know it works fine, I just don't want to burn up the motor or start any fires, ya know?!! Thanks for any input you guys can help me with!!

Greg,

No don't appologize for the long post. I would MUCH rather have someone long-winded than a three word reply!!! I didn't even think about running it right from the battery. I just assumed (yeah I know) that it had to be fused like everyting else, but I suppose an inline fule would do the same huh?

I now have the tailgate mounted and can "roll" it up and down with a battery. My only real concern is that there are four wires coming out of the 'gate. When I hook the negative up to the black wire, either a blue or white rolls the window up or down. There is a third red wire that doesn't seem to do anything, any idea what that is for? I would think that if it were for the key to operate the window it would have a pair of wires?

Anyways, I assume (here I go again) that the black should be grounded to the body and the blue & white would be taken forward to the swich... so whouldn't I have a three terminal swich? One coming in from the battery and two for the swich? Thanks for the advice, I REALLY appreciate it!!!

Sorry for the delay in getting back to you guys, I got caught up in Honey-DUE's!! I could not find a momentary switch that was three way for some reason, so I just got a standard 3-way switch. Maybe at a later date I will find one, but for now that will have to work. I did get it wired up outside of the vehicle just to make sure it worked. To my surprise it did just great!! I can't tell you guys how much I appreciate your help!! Thanks so much!!

I do have one last question before I finish the job though. The wire I currently have to use is 14 awg., the wire from the tailgate appears to be 12 awg. (it is just slightly larger than my 14) and the largest inline fuse I could find (which is 30 amp) only came in 14 awg. Will that be alright? The window seemed to work just fine, but should I go get 12 awg. and/or keep looking for a larger fuse? Thanks again!!!
