Where do I find that?

Prince Gitau

Its on the Vehicle Identification Plate in the hood and is also stamped on the Engine Block.
It should be three letters like "AHA" should be below the Chassis number. Or just give me all the info on the I.D plate... That I can upload the wiring & relay block specific to your car.

AHA is the only 30V v6 available in the US. So who cares about the engine code. Ill get some time and look over some diagrams.

Hey guys, Prospeeder & Lumpydo was just clarrifying coz on my side we have all the three 2.8L engines scattered on our roads..if we put our heads together we'll get this sorted...

Check out this address below its my secret manual where I get solid info on my cars.. Its always wise to start with a scan of your vehicle it'll point you in the right direction.

Fyi;
Terminals 30 & 15 are Positive Bus i.e components requiring power are connected to either of these points.

>Terminal 30 is always powered so long as the battery is connected.
>Terminal 15 is ONLY powered when the key is in the ON position

With the aid of a tester or multimeter you may want to start by verrifying where your ignition relay and other ignition related relays are getting their power from. It should be from Terminal 15

If all are well, inspect for effects of heating on cables around relay blocks. What we are looking for is any damaged cable that's supplying our ignition block with power from Terminal 30 ilegally.

If you are well aquainted with auto electrics you may proceed. If you are not sure, ask a pal/technician who is to help you out.
The links around have all connections you"ll need for the assignment - actually its the entire manual for your car if you brouse around the links.
All the best.
