berginr,
Thanks for the diagram but I'm lost to what you're saying. What do you mean by "Long story short jump grn/wht pin 12 to wht/grn pin 22(at the tcm)"?

Sorry ok what i want you to do is jump the grn/wht wire going to the tcm connector c438 pin 12 to wht/grn wire connector c437 pin 22.Use the connector view i got that is a view from the back side of the connector(connectors plugged in).Use 2 safety pins and a jump wire hit the brake and see if you can get it out of park if this works butt connect the wires to gather.

The link you sent me thy are trying to fix the bulb.We will get to that later.

double check you have the rite pin,wire color,and connector before you jump them

So this is what you want me to do in other words:

1) Cut the white/green wire(c437, pin 22) from the TCM connector

2) Cut the green/white wire(c438, pin 12) from the TCM connector

3) Connector those 2 wires together?

Just want to make sure that's what you're saying before I do anything. One more thing, the diagram of the 95 prelude is the H22a TCM right? If yes, can you also show me a diagram/pinouts of the prelude's connectors/tcm like the one on the Accords.

Yes rite(i have double checked 7 times just to be shure) but don't cut them just yet), jump them together with a jump wire and 2 safety pins you can put the pins in the back of the connectors.If it works you should be able to get out of park when you hit the brake.Then butt connect them.

The last post is the 93 accord.

You are using the h22 motor,trans and the tcm but the 93 accord wiring harness rite?(Im double checking)?

Then we will look at the d4 light.

Its for the h22,h23 and the f.All the interlock systems are the same on the 95lude dont be confused we are not working with the a/t system.The a/t systems from the h22,h23 and f are very different.

Here is the 95 lude.The 95 diagram is up above.

Now if you look close you will see the pins and wires are all in the same place(the connectors are labeled different lude is c441,c410 the accord c438,c437 but thy are both the same pin count and both fit into the tcm one is a 22pin one a 26 pin).The problem is here the lude uses a capacitor and the accord a relay.

We have to get around the lude tcm it is not supplying 12v to the accord relay it is supplying a very small amp flow to fire the capacitor.

One final q did it all work before you did the swap?

We are both nuts you know going crazy over getting out of park.I think the d4 light will go easyer.

Yes, I'm using a H22 motor, trans, and ecu, tcm, and the stock 93 Accord wiring harness. So, you're saying I need to use a extra wire with 2 safety pins at the end of that wire and use those 2 safety pins to connect to the back of the plug connectors, right? Let me try to draw you a picture of what I'm talking about...or maybe you can do that too...

this is what you're talking about right? Sorry if I'm not understanding. Here's a drawing attached.

Yes before I had the H22a swap, everything was working fine.

rite you got it we are testing if it will work not making it permanent yet.Use safety pins not paper clips(you know baby diaper pins or a sowing needle).This way if it will not work you will not have 2 cut wires.I am 90% on this let me know what happens.

You should be able to hit the brake and get out of park.If it works cutem then but connect em(permanently)the safety pins and jump wire are temporary just for testing.

Its a method i use at work its called back probing thy make special back probing tools but thy are just a sharp pin that fits in the back of the connector and have a little alligator clip on the rear.

You must think im nuts lol.Next i will be telling you to fix stuff with gum and duck tape lol.
