No key and the trunk lock on he dash has been drilled out. Is there a way to jump the trunk open? I can access the underside of the dash. Thanks!

I don't know the year of your car but in case of a 98-00, you can open the trunk activating the release motor. In order to do that, access the MPX body network computer and ground the pin 17 of connector D which is connected to the release lever.

In case of a 95-97, it's the pin 17 of connector C. Sorry that I don't know about a 90-94.

You've heard the OnStar commercial?

Well BlondStar is where the woman calls in and says; "I'm locked in the car and the keys are on the hood".

Sorry about that...93 LS 400. When I find the right connector/pin how do I ground it? Add a wire to the pin, replace the connector and touch the wire to sheet metal?Thanks!

Lol! How do I "ground a pin"? Just add a wire and touch the end to sheet metal? Can I find the appropriate pin in the owner's manual? Thanks!

Default 1993 LS400 where is the MPX body computer connector/pin for trunk release?

Yes. I locked my keys in the trunk! Also how do I ground the pin to release the trunk? Thanks!
(Sorry for the double post but wanted to post a more specific question)

And you will need to know is that view looking at the connector still plugged into the ecu or after its disconnected looking into the end? And do you leave it connected to the ecu when doing the grounding or unplug it before doing the grounding? And if you do have to unplug then the battery needs to be disconnected before unplugging or reconnecting it. And maybe I'm adding more complexity to nothing here, but its need to know stuff that was not included.

And yes you would have one end to a good ground on the car, you would find the location in the shop manual not the owners manual.
Manual on the Toyota site if you need it.

1993 is a gen 1 and as far as I know all gen 1's do not have that computer. You would just jumper the key switch that is down near the trunk release. That means gaining access to the back of the switch to remove the connector to jump it. The key switch just disconnects the trunk release switch so it won't work, so you are basically bypassing the key switch to make the normal release work.

I find that you are a guy who don't inform the detail and asking for a help to rest of us. You should have informed us at least the year and the situation of the current status.

So you can access the connector. Then it's quite easy. Just make a short circuit between the contacts using a paper clip or a jumper wire.

I apologize for any confusion. I added the year after your first reply. I wish you had insisted that I provide the year before replying so as to not waste your time. Thanks for your help.

Thanks! I was able to pop the trunk by inserting a wire where the wires go into the back of the connector (wire harness) to the trunk release. By trial and error I jumped several combinations between the four wires til the trunk opened. I didn't need to remove the connector from the back of the trunk release. Sorry, again for not including the year in my first post and for any inconvenience that caused.
