7.3 IDI E4OD Stand Alone Computer

Hello, I’m going to be installing a stand alone computer for the E4OD soon and I’m familiar with some wiring but just need some help locating a 12v under the hood that has power being supplied during cranking and running. They say to use an ignition switched power wire

Check your fuse block for 12V ignition. Use a fuse tap and run the wire through the firewall to the controller.

On the IDI, the fuel shutoff solenoid is On when key is On. There are a couple more and they all appear at the big Engine Connector at the passenger side inner fender.

when I first run it in drive it shifts normal in D for about 10 minutes then neutrals/ stays in clutch and will somewhat shift if I hit 3500 rpm but hard, when it does all that recently I've been taking the cap plug thing off that shuts the tach and everything off and I can manualy go 2nd to 3rd but I guess it need electronics to go into 1st manually because it works when plug is in, I would drive it like that but I cant pull trailer without first gear.

Just use the constant 12v source from the EEC relay. It’s already intended for your transmission controller/trans so why not reuse it?

Failed range sensor. (formerly called the MLPS) the large sensor located on the shift lever. Drivers side of trans.

Exactly what I would use also.
(Don't forget to clip that stupid fuel heater line that's cheaply tied into this circuit! Like should be done to all IDI/E4OD trucks. To those who think they need a fuel filter heater, besides probably being wrong haha; run a new fused line for it. To those wise; not only cut it's power, but tap and plug it too! To those most stubborn; Fine, keep a fuel heater, but run your own fused line if you have the E4OD, tap and plug the oem leak point and get a universal wrap style filter instead.)
