bypassing interlock system

Here's what I'd do---I actually looked, and found no diagram The following tests are based on two possibilities:

On a car with no interlock, the start path goes battery---ign sw--twist to "start" ---start signal to starter relay----relay ground through park/ neutral safety switch

There are two possibilities:



1 Chrysler could have placed the interlock to interrupt the starter relay GROUND, that is, between the relay and the neutral safety switch

2 Chrysler could have put the interlock between the ign sw and the starter relay



1. Disconnect the battery, disconnect the underseat connections, and disconnect the relay under the hood

2. Now use an ohmeter/ continuity light on the interlock connector terminals one at a time. See if any of them go to one or the other of the push-on terminals on the starter relay. I would bet one of them does. Note the color and see if they are the same at both ends.

Now we must figure if this wire must go to ground or to power

3. Reconnect the battery and the two terminals on the starter relay. Make sure the car is in park, have a helper hold the key in "start."

4. Pull one wire off the start relay. Probe the WIRE you removed for power in "start". If none, leave it off.

Now ground the exposed starter relay terminal and see if the engine cranks. If it does move to step 6

5. If the disconnected wire shows power, connect to the relay, pull off the opposite wire. Ground the terminal you just exposed. The engine should crank. If so, move to setp 6

6. If you get this far, it means the interlock relay is in the "ground" circuit of the starter relay.

Now connect that wire back up to the starter relay, move to the interlock relay,

AND YOU SHOULD FIND that the last wire you just played with is the same color--same wire--that you noted earlier

What all this just "found" is that the starter relay goes to ground through the interlock and on to the neutral start relay on the trans.

7. So now, disconnect the interlock, make sure the starter relay is again hooked up

Probe the wire you previously found at the interlock connector with voltmeter or test light to ground, while twisting the key to "start" you should get a light. Further test this by grounding the wire, and the engine should start NOTE THIS WIRE

If so, all we must do if find the path to the neutral start switch.

First look over the harness, or look over your diagram, and see if the neutral start switch colors "come up" to this connector (interlock relay.) confirm by probing the connector-----

Disconnect the battery, and with your helper able to go from drive--to park--to neutral, see if there's a wire at the interlock connector that grounds as the shifter goes to park/ neutral.

IF this happens, now all you must to is permanently jumper this last wire to the one you found in step 7.

IF NONE OF THIS WORKS it means the interlock relay is interrupting the start signal from the ign switch, instead of being in the ground circuit

So------

1a. Disconnect the interlock relay, have a helper twist/ release the key while you probe the connector for voltage IN THE START position.

If you find it, this is probably then routed to the start relay NOTE THIS WIRE

2a Disconnect the battery disconnect the push on wires from the start relay, use an ohmeter/ continuity checker to probe the interlock connector and find the wire that goes from there to the start relay.

3a Check your work by jumpering this last wire in the connector to the wire found in 1a

The engine should crank, and should not crank in drive. If this is the case, just permanently jumper / splice these two together
