Post Trans plug

Got a question about a th 250c trans. On my 84 Monte i yanked my 6 and put a goodwrench 350 in it. The old motor was computer controlled and there is a plug that goes into the side of the trans. Since my new motor will not be computer controlled i'm not sure what to do with this plug. There's 4 wires that come from it and on accident i cut them while pulling the old motor <img src="graemlins/spank.gif" border="0" alt="[spank]" /> I believe the plug has something to do with the converter lockup but i'm a little hazy on what it does exactly. If anyone could help me out and let me know what to do with these wires i would greatly appreciate it. Thanks
Nick

I'll take a shot at an answer. Those wires are, as you thought, for the lock up converter. I just rebuilt a 200R4 and set it up with my non-computerized '62 Chevy 235 6-cylinder. Check with bowtieoverdrives.com They have a wiring harness and pressure switch that will do this conversion for you so your converter will lock and unlock at the proper times and you won't need to give up that great feature.

Thanks alot for the info, I really don't have $70 to spend now since I'm in school but I think if i find a diagram i can probably make my own with a brake swith, toggle and a relay. I was doing some more searching to find out more and i read that it really only affects the gas mileage and makes the trans run hotter if it's not hooked up but I've learned that heat is not the friend of any trans especially mine since it's got 96K miles on it. Thanks again
Nick

Willys 36, you said you just put a 200R4 on a 6 cyl 235. How did you adapt the tranny to the 235? I would like to use the 200 with the 61 235 in my 48 Chevy 5 window, but have heard horror stories about the adaptors used in this conversion. <img src="confused.gif" border="0">

Got my adaptor from <a href="http://www.stoveboltengineco.com" target="_blank">www.stoveboltengineco.com</a>

I have heard horror stories too about all kinds of modifications but discount a lot of them as urban legend. I don't plan on putting 6000 hp thru my adaptor so am not concerned.
