i just picked up one and i started the install tonight but im confused on what wire is the pos+ and what one is the ground. there is a solid black and a black/white

 

Just touch each of them to each terminal on your battery carefully. If it doesn't light up swap the posts. Problem solved....

 

that will work? it wount screw it up?

 

if i am correct, you could touch the leads to either terminal and the light will turn on.

Just be sure the "light off" button is not clicked. I almost tore my dash apart when I installed mine becuase I didn't check that button first.

 

btw Toyota does make a harness that is plug and play for the inclinometer lighting. Goes between the wiring.

*edit* Found a pic:

They are only $15 or so, but very hard to find. According to my Local Toyota dealer, I got the last new one in the US. That may or may not be true, so check with your local dealer.

 

mines already torn apart lol i am replacing my dash too cuz its all cracked, so i found a good dash and found an inclometer too. it should look good in the truck.

 

no thanks on the plug im just going to splice in to dash light circut.
