. . Hello again, , Getting the new 700r4 ready to install. . Question is how to wire for power. . Some I talked to say add an on/off switch. . Talked with one guy who wired his to the hot side on the ignition switch. . That sounds like easier operation. .
. . Any thoughts? ?

The kit is fine for someone with limited knowledge and parts. The converter solenoid is already in your trans, so that is not needed. The relay and associated wires are not needed unless you want to lockup in 2&3. I personally don't see why someone would want to lock up in 2 or 3rd, however I am open to ideas. In any case, locking up in tow modes is asking for trouble. So what do you need from this kit? The pressure switch, side connector if you don't have one, and dual brake switch and if you don't want to make a small harness the wire that goes from the side case connector, to the pressure switch and then to the solenoid. Seems like a lot for $129, however, again, if you don't have the stuff or want to make the harness, it is probably worth it.

. . Thanks. . The transmission is already wired for a single lead conversion. . Already have the double brake light switch. . Just thinking about where I want the power sourced. .

You need ignition power. Fuse block ignition terminal or ignition switch would both work.

I know lots of people say it works great, but I absolutely hated the 700R4 I ran for a short time which was setup to get power and lockup when it shifted to 4th. It was a huge drop and the kickdown was a big jump up. At the least put a easy to reach toggle. You'll like it much better if you drop out the TCC if you need a little extra or are climbing a small hill instead of having to kick it down to get it out of lockup.

Power comes from the break light switch. That's why when you tap the brakes it comes out of lockup like the factory. The power to the solenoid is in series through the pressure switch. The dual switch has one power point on, one power point off.

. . Thank you. . You mentioned something that everyone else failed to mention. . Forth and lockup at the same time causing a big drop. .
. . I think the best idea is a lighted rocker switch, but where? ? Don't want to cut any holes in the console or cover. . Maybe inside the ash tray hole? ?

Fourth and lockup do not happen at the same time unless you have the wrong pressure switch. Lockup changes the RPM about 2-300 rpm only. The trans goes in fourth, builds enough pressure to activate the pressure switch then goes into lockup. If you are concerned about lockup you can intercept the switch and do it when you want it, or put in a higher pressure switch. Also keep in mind that part of the cooling of that trans goes through the convertor goes through the TCC solenoid. Also if you are very concerned about gear ratios you might want to consider some changes in the trans that have nothing to do with lockup.
