i have a 5177 NOS kit, with the WOT switch and Fuel Pressure switch. I also have an inline a1000 fuel pump that becomes activated at 2,000 rpms using an MSD rpm activated switch. So it's already hooked up to the rpm source, whatever that is. Anyways, can i use a distributor block to split this RPM source to my window switch? and how about the 12v, can i splice into that as well? thanks.

 

anyone? what would be the best way to splice into the wires? and is it gonna cripple the performance of either unit.

 

I used tap connectors I got at radioshack. Worked good for me

 

Here you go here

 

Ok, do not use a scotch lock they have been none to come loose. Just strip a little insulation away from were you wnat to connect and splice your wire in.
Here is the drawing for connection. and the 12 volt soure can come from you arming switch the micro switch.

Hope this helps.

any idea on the gauge of the wires?

 

I have two msd switches one window and one activation off the same tach wire, no problemos. Used the same 12v wire also.
