Need help wiring on/off switch for speedcal

[jgt58]

Backstory. Basically my speedcal is draining my battery. No I dont wanna disconnect the battery every time I put it up for a couple of weeks. I want to wire a o. Off switch between the speedcal and the cig lighter. Any help would be appreciated as I am not an electrical expert.

Wire switch inline of the 12v+ for the cig lighter, or swap out the Speedcal/find actual issue.

Oh its the speedcal. I had not one problem with my battery till this happened. I have a Optima red top if that helps

I also would be willing to wager it is the speedcal. Mine will drain my battery if I leave it for a week or two. I just always leave my car hooked up to a battery tender if it is going to be sitting a while..

Ya..i guess the cig lighter is constant on for the 96-99.

I ran my speedcal through the traction control.

I would run your speedcal power through some other switched fuse using a piggy back fuse holder in that slot. Maybe the unused convertible top fuse...i think that was the one that I used to run my cigarette lighter//armrest power later..

I use my power seat connector as constant 12 now...

Why don't you just wire the power to a switched 12v source instead of a constant 12 like they recommend?

Reccomendations?

Any switched 12v source should be fine. The switched 12 for the radio is probably the easiest.

Gotcha. I thought radios are always on for memory?

Just a few
12v switched wire at the radio
12v at ignition
12v available at the fog light switch
12v at the convertible top switch

I had the same issue of dead battery after the speed-cal install. After I swapped the power to a switched 12v the issue went away. I used the Radio's switched 12v source.

Do you have an aftermarket radio?

You can use either the red wire or the blue wire (the blue wire may have a white stripe, but there's only 1 blue) on the aftermarket radio harness.
