Brake switch?
 

Can anyone tell me if I have this wired up correctly please. I'm using a 4l60e out of a camaro.

Re: Brake switch?
 

You need to add a switched B+ source to that vacant terminal behind the TCC wire, so that you have constant power to the TCC solenoid until the brake pedal is applied. Yes, you have it wired correctly

I thought the feed in was what supplied the power. Where do you suggest I get theconstant power from? Ignition switch?

I also have an orange park neutral wire I need figure what to conmect it to. Right now I have it grounded.

Re: Brake switch?
 

Is that purple wire from your LS harness (I believe mine was, I'll have to check)? That's just a feed to the PCM, then to the TCC lock-up solenoid. Your trans. cable is routed from the PCM. You can tap off of your fuse panel for switched power. On the left side of your fuse block you should see two single pin terminals marked ign., they are switched power sources from your ign. switch

I suppose I should ask "What year is your truck"? I'm using my '80 for reference. Also, I'm not sure about that orange wire you mentioned, as my truck was originally a stick truck, and I used my clutch safety switch wiring for my neutral safety hook-up from my Lokar shifter. I can check AllData to see if maybe the range switch on the trans. uses an orange wire for park/neutral if you'd like

It is a 70 but I'musing an aftermarket harness.

Re: Brake switch?
 

You need a wire that has power when the key is on to attach to the plug next to your purple TCC wire from your EFI harness. You can use one of the spade plugs on your fuse panel, but choose one that only has power when the key is on.

I have a keyed ignition spot open on my fuse panel that I can use.

Thanks guys
