ok, ive got a 84 toyota and the bed was trash, i bought another bed today that is a off a 90 and like i thought the tail lights don't work from my 84 so i have to order new tail lights for this year bed, but what i'm wondering is will the wiring harness on my 84 gonna plug straight up to the 90's model lights????

 

I think they are different but without both to look at hard to tell.

It would not be hard to solder and heat shrink the correct ends onto what ever is easier .

In a worst case use insulated spade connectors and do each wire individual

 

Concur

 

i figured it would come to that just didnt know if anyone one would see this thread that had the same bed and harness, thanks for your time
