Its 2003 highlander without t harness. Sorry cant give you service number right now up to work right now thats why.

This car has 2 ignitions, 2 starter wires, and 1 accessory. Not sure how you wired all that up since it's not shown in the guide. 

 

1 - redo the ground.

2 - have only 12V and ground connected to the unit and you will need to test the ignition, start, and accessory outputs of the EVO. This means, disconnecting pink,yellow and white from the car. This is to see if any of those outputs have power on them when you connect only 12V and ground to the EVO. 

 

 

I did check the pink, yellow and white wires. They are live wires with only the 12v wire and ground connected. Is something wrong with the module? Service number is 002BO7 29316.
Any answer
Did not see your previously reply.

 

If you have power on those other wires with only red and black connected, you will have to contact the original place of purchase to have the unit replaced. Also, before reconnecting a new unit in there, go over the install. Those are 30Amp relays in the evo, if they blew (latched in the Open position), something was very wrong.
