Wiring Indicator Light into Circuit

I haved added a manual on/off switch between the brake NC output and my TC lockup vacuum switch circuit on a TH200 4R. This allows me to disable the lockup feature at low speeds to keep the engine from lugging or constantly locking/unlocking on winding country roads in OD.

I would like to add a small indicator light next to the switch (a green mini light that will be on when the LU is engaged).

Do I just tap into the lead coming out of the manual switch to get power for the light, and ground the other lead from the light (i.e., a parrellel circuit to the TC vacuum switch and solenoid)?

John

Why not try a switch that has the indicator light already built into it? I have a manual switch that I use to force on the relay that controls my engine cooling fan in the event the thermostatic control goes south. The switch has an indicator light built into the end of the switch lever that glows green when the switch is on. I bought mine at an auto parts store but I've also seen them in Wal-Mart.

Doc here,

If you don't want to go with the lighted switch (which is a good Idea also..)...

You need to get a 12 volt L.E.D. high intensity green, hook the cathode side to the switch where the TCC wire ties in, The other side to a hard ground. That will do the job.

I mention the H.T. L.E.D. because it is small, bright and requires no load resistor, is about $5 bucks and will last 50 years!

cuc and Doc,

Thanks for the replies. I did look at some of the lighted switchs but I wanted a rocker not a toggle because the switch will be located just above my knee under the dash and I didn't want to be hitting it. And I was kind of anxious to do it this past weekend so I went with a plain rocker without looking much further.

I believe I will look for either a rocker with a green light on one side or the LED Doc suggested. Right now the switch works fine, but it does need some indication of which way is the operable position.

Thanks,

John
