Fuse block Bulk head harness

RoryH19 · Jan 14, 2020

Hello,

What year did the fuse block change from round tube to the blade style?
Assuming somewhere between 79 - 81.

Any issues in retrofitting the later blade style into the older trucks?
I would change the harness inside the cab and under the hood.

Thanks

It changed in 1978

I saw a 78 on sat, still had the tube style. Verified via the vin. Maybe 78 had both.

I used most of a 1985 wiring harness in my '76. Older headlight harness plugged in with no issues.

You will have issues with the windshield wiper switch, unless you use the newer column. High beam switch on the floor is an easy rewire.

I was thinking to use 81 - 83.
That way it has the same style dash mounted wiper switch. It would also keep the floor dimmer switch.

79 has the blade style fuses. Dimmer switch on the floor and dash mounted wiper switch.
