If you are not sure you can just to ask us if we know, email us with the vehicle information (Make, Model, Engine size and Year) of the donor vehicle that your PCM/ECM came from. 

Any GM PCM/ECM made from 1986 to 2002 could be a PASSkey type VATS system, which our bypass module would work on.

If the vehicle that the PCM/ECM was made for had the black resistor pellet in the metal part of the ignition key then yours should be the PASSkeyII type system - Our bypass module SHOULD work for you.  You should still email us with the vehicle information (Make, Model, Engine size and Year) so that we can confirm for you.

From 1986 to 93 some PCMs used a 30 Hz version of the VATS signal, the only way to know if yours is this type is if it is on our known 30 Hz list.  We have both versions available, the standard as well as the 30 Hz.  If you order the standard VATS bypass or the 30 Hz VATS bypass module and find out later that you needed the other type, you can send it back for exchage as long as it is still in like new condition.  You will have to pay for re-shipping.  If you are not sure as to which you need we highly recommend that you puchase the DFVATS.  The DFVATS (Dual-Frequency VATS) has both signals types, all in one module.

The VATS signal wire will be labeled (in your vehicles service manual) as VATS, Fuel enable wire or circuit number 229 and is normally a dark blue wire.  The pin number at the PCM varies depending on application:

TBI/TPI 89-92 -------- pin# B6 (might be a white wire instead of dark blue)

TBI/TPI 91-92--------- pin# F10 of the ECM's 32pin E-F connector.

LT1 92-93 -------------- pin# 19 ("A19") of the PCM's 32 pin red connector

LT1 94-97 -------------- pin# 25 ("A25") of the PCM's 32 pin red connector

LS1 1998 --------------- pin# 11 of the PCM's 80 pin red connector

LS1 99-02 -------------- pin# 30 of the PCM's 80 pin red connector

3.8L V6 95-97 -------- pin# 55 of the blue PCM connector

3.4L DOHC V6 95 ---pin# A14

PCM# 16187424 -----pin# D6 of the PCM's C3 connector

 

If your Pin location is different from that listed above Please let us know so that we may update our information.

 

The VATS/Fuel enable wire can also be found on the BCM’s 10 pin blue connector, at position 'E' or position A3 .  In older vehicles the BCM may be called the TDM (Theft Deterrent Module), CCM or PASSkeyII/VATS decoder module. 

No, as long as your are using a remote start system to enable the starter our VATS bypass module is all that you will need.  The security warning light may come on, if you wish to diable it just cut the wire that goes from the BCM to this light.

If this is the complete system (all the other computer modules are still there)  your vehicle may also disable cranking, our module only enables the fuel injectors.  If this is the case, you will need to find and bypass the crank enable/disable relay by rewiring this relay (add a jumper across it) or you can bypass it by using another relay or remote start system to activate the starter solenoid when the ignition key is in the cranking position. 

Also the security warning light may still come on, the easiest thing to do is just cut the wire that goes from the BCM to this light.
