I have a toyota 4runner 1991 I changed the engine to place a 3.4 everything is fine for the engine starts and everything but its light side that it does not work .. my alternator does not charge, I have no break light, no cluster light, radio and fan does not work either I just miss it to be able to run the jeep does it happen to someone I'm not able to find the problem ... help please !!

 

All grounds in good shape, and cleaned down to bare, shiny metal on bare, shiny metal?

 

yes I buy them all in new yesterday and i change them

 

So you did an engine swap and some lights don't work.

 

You will need to dig into the wiring schematics a bit more. I don't have the 91 manual in front of me.

There will be a few switched power lines that come out of the ignition switch, that may or may not supply your alternator.

The driving lights should have constant power (they are switched ground circuits) so start at the lamp holder and work your way back along the signal until you find where the power is cut.

 

yes, I apologize if I do not say the right words I do not speak much English .. so I change my engine 22re for a 3.4 I made everything but I get to the wiring and get stock there ..my light cluster does not work no radio no fan, no break light I change everything my ground well sanded and install I check all the relay all my fuse .. and there is also my alternator that does not charge .. it's been about a week that I search and try a lot of things but I do not find the problem

 

ok thanks i will try that
