Ez wireing install in 74 40

[nitroid13]

I got the tail lights wired up and ran on the back of the truck also got the license plate light wired as well







Ran on the left side frame rail



Had to splice the plate light wire to the right park and is far too long so you can't run the driver side plate now on ones that have the plate on the right side of the truck you have no problems at all




How there ran to the lights

I have got the park lights on the front working good and rears also have the side body lights on and working. Now on to the blinkers but I might have to put my van column in but to get that to work I have to rekey it( word of advice don't get a column from a junk yard w/o a key) lol. Also does any body know how to ohm a switch with a volt meter and what to set the dial to. I'm trying to get the rev switch to work and it's like it's stuck in rev and the tranny is in nutral. I'll have pics Tomarrow night of them

Update I now have brake, tail, turn, and rev lights . Funny enough I had the flasher wires crossed and now every thing works great and I also put in a gm headlight switch for ease of replacement and use. Would much rather my orginal but it crapped out on me and now on to getting all the gauges to work and wireing up the alt and voltage regulater so ill have a charging system. I do need some help tho I need a wiring diagram to wire up the alt plz help. Then it will be on to wipers and then a blower motor for heat and then a radio

And I'm about to take the front cap off to replace the finders with good ones and finish the powersteering upgrade in the process

I do need some help tho I need a wiring diagram to wire up the alt plz help.

This is pretty simple:
Run key on power from a 10A (or more) fuse to the Ign terminal (black wire w/yellow stripe) of the voltage regulator located on the firewall beneath the brake booster. You can either keep the original two wires from the VR to the alternator or replace them with new wire.

How do I test my temp gauge to see if it works? I have an ohm meter as well

 

[Pin_Head]

Ground the sender wire momentarily and see if the meter deflects high. If so, then the meter circuit works, so just hook it up and see if it reads right by comparing it with a real thermometer.

Good work. I used the same kit with no issues. There is a little thought involved and some extra wires that need to be added if you are going to use the Toyota switches, but it's not hard and certainly worth figuring out. If anyone needs help, PM me.
