#1 I read about this mod where you splice a switch into the tranny line pressure control resistor. (that thing mounted right next to airbox on strut tower) It will give firmer shifts like a vb upgrade but may not be as safe. Say i use it once in a while will it really hurt my tranny? I have a Hayden tranny cooler.

#2 How can I run a neon light rod behind grill. Can it be connected to the battery and can i use a switch.

 

1) don't do it all the time, and your fine

2) no idea.
