h4 the 3 pin halogen ones

you can purchase a wiring kit that plugs into existing factory wiring for about 20 bucks saves alot of time and trouble

weak fuel pump, clogged injectors, air or coolant temp sensors out of specs. Timing belt was put on wrong. Timing is off. Map sensor out of specs. You do have a light on. Fixing why the light is on may fix your problem.

Remember call parts department for Toyota and they can fax a copy to you or you can pick it up from them Also ask about wiring diagram same thing
