do a google search.....a lot written on how to wire it
Rules says.......Never once ever had a tech inspector look at the wiring of the delay box...transbrake or line lock....
I still don't understand why a line loc would need to be used with a transbrake unless the transmission needed to be fixed. Why would you want a brake dragging after investing in a transbrake that releases in a few thousandths of a second and smacks the tire consistantly?
Most of my racing was at places that looked at your car, back when they cared. Not every thing every week, but they would look at random stuff pretty closely sometimes. And I've been spot checked on the return road for odds and ends. And if you got caught with something bogus, you'd likely get the rest of the year off.
Funny thing is, when you do stuff the way it's supposed to be done, whether it's going to be looked at or whether it's in the rulebook, or not, it usually works out better. All I can do is tell you what's right. It's up to you what you do with it.
