Power Lock - PINK / YELLOW @ Driver door harness in kick panel
Power Unlock - PINK/GREEN @ Driver door harness in kick panel

the system is postive triggers if the car came with factory keyless entry remotes, if not they are 5-wire aka reverse polarity.

if the car has factory keyless entry, connect the unlock and lock wires from the main unit straight to the lock and unlock wires on the car. Just make sure the outputs on the unit ARE POSITIVE

if they are 5-wire rev polarity, then wire it up like so. you need 2 relays.

Relay 1 (Lock)

85 - lock pulse from alarm (-) *
86 - constant 12v
87 - constant 12v
87a - cut lock wire on car connect switch side to this terminal
30 - the cut lock wire on car motor side

Relay 2 (Unlock)

85 - unlock pulse from alarm (-) *
86 - constant 12v
87 - constant 12v
87a - cut lock wire on car connect switch side to this terminal
30 - the cut lock wire on car motor side

if the ouputs from the main unit are ONLY postive then on both relays, change 86 to Ground

if the vehicle is equiped w/factory keyless then you can run 3 wires into drivers door to factory switch

Pink /Light green (+) Lock

Pink / YELLOW (+) unlock

Blue /white (-) Disarm

if no factory keyless then you will need to use relays as described above

okay time to regroup,

1 do you have a volt meter?

2 do you have a factory keyless entry system on the car?

3 what wires are you tied into that are blowing the fuses?

you must identify the type of locks you have, either reverse polarity or Positive triggers, then you must test with the volt meter to be sure by operating the locks and reading the voltage. But let me know about the first 3 questions and I can get you all the info you need, also direct email will be faster shark@efni.com

good luck
