Installing a transponder


#1

Okay, dumb question…

I am doing Comp School next Friday and will be making my racing debut the next day. I have ordered my transponder through NASA so it should be at the track when I get there. What do I need to bring to install it in my car?

Thanks.

decide on your source for +12v and ground, you’ll need electrical splicers and tie wraps (at the least) to attach it somewhere.
Some say to attach it to a switched 12v but I just have mine wired to the +12v point on the dist block on the firewall on psgr side - it doesn’t draw that much and I flip off my cutoff switch when the car is in storage.
cheers,
bruce

Did you buy a wired version or the battery powered kind? If battery powered, you just need zip ties pretty much. If wired, you just need some wire connectors and a bolt-through connector to run a ground to an odd bolt.

I actually have no idea. I guess I should ask NASA which one they sell. I didn’t realize there were battery-powered versions.

Bill,

It’s probably the wired one (less expensive) which is fine. They’re easy to install. Chuck and I are experts because we had to wire, re-wire, re-wire, and re-wire ours at Road Atlanta last year (when we took the comp school).

I can help you do it when I get there Friday afternoon… the hot washer fluid line is a good place to get power. Grounds easy, and there is a nice place for it behind the passenger side headlights.

Great, thanks! I suck at electrical stuff, so I’ll probably kill myself or set the car on fire if I try doing it alone.

Guys, this could be a good thing. Remember that Bill has been Peachtree HPDE champion for a long time running. I’m just sayin.

I actually agree with that.

But we’ll see how fast she is in a momentum car…

I heard the trick setup was to mount it on the rear bumper. It’s much easier to pick up power since the battery is in the trunk.

Yes, that is the ideal spot.

No need to worry about me. I will be puttering around the back of the field at RA, just getting my feet wet. So it doesn’t matter where I install it!

That’s what they all say… And then once they put the big boy pants on, they start talking smack about winning 6th place… You’ll be there soon.

All joking aside…You want this puppy to work…I have to chase people every event because the TX is not hitting. You want low and with a clear shot to the loop which is UNDER the pavement on the track…It is also a transmitter and is voltage sensitive so give it a solid lead for power. Do it right the first time. Switched is OK, BUT remember to flip the switch or you start from the back.
