    Hi,.. I was given a remote starter kill relay (part # 6402A) along with the key fob remote. I want to install it on my 84 Dodge Rampage mini truck but there is no schematic on the outside of this 4 pin relay showing the internals and none of the pins are numbered so I am at a loss as to which pin goes where. I could not find this info in a search.  All I know is that it came out of a late model GM vehicle and the 4 terminal pins are located closer to one side than the other. I havent run into any GM vehicles lately or I could have removed the factory starter relay and test lighted the female terminals in the relay center to i.d. which pin goes where. Can anyone help with identifying these for pins? Thanks.

You pull the relay from your main fuse box usually under the hood and place the new one in there.

1. The vehicle must NOT be running.
2. Disconnect or pull the factory immobilization
relay from the vehicle.
3. Examine the footprint of the factory relay and
match it to the correct SSKR from the application
guide.
4. Install the SSKR in the same receptacle that
you pulled the factory immobilization relay
from.
5. Wait 30-seconds to allow the SSKR to arm
itself.
6. Attempt to start the vehicle. The vehicle
should not start if the SSKR is armed.
Note: If you do not have a transmitter programmed to
the SSKR, refer to the ‘Programming’ section of this
guide, program the transmitter and continue with step 7.
7. Use the transmitter to disarm the SSKR and
start the vehicle.
8. If successful, place the factory relay in the
glove box or console for replacement in case
of vehicle ownership change.

Programming Transmitters
1. With the SSKR installed in the vehicle,
attempt to start the vehicle to verify the
SSKR is armed (the vehicle should not start).
2. If vehicle starts, turn the key to the OFF position
and wait 30-seconds for the SSKR to
passively arm.
3. Upon arming, cycle the key from the OFF position
to the START position 3-times and HOLD
the key at the START position on the 4th turn.
4. While holding the key press button 2 on the
transmitter within 2-seconds of completion of
step 3. The vehicle should now start. The
transmitter has been learned.
5. Turn the key to OFF and wait at least 30-
seconds.
6. Try to start the vehicle with the key. The
vehicle should not start.
7. Press button 2 of the transmitter (to disarm
the system). The vehicle should now start.

All good information but only useable after I adapt the relay to the 84 Rampage.  posted_image ,...... still need to know what pin on the 6402A relay does what. Anybody ever checked ( i.d.) the female socket terminals for the immobilization relay on late GM vehicles. Evidently,..This is the only way to i.d. which pin does what on the 6402A SSKR relay. Remember,..this relay is being adapted to fit an earlier 84 Dodge Rampage. I already know where the stock Rampage starter relay is and it's pin terminal wiring and but dont know the pin terminal i.d. schematic on the unlabeled 6402A relay.
