i need info on where to connect the white and the yellow wires out of the loose wires from the main harness. yellow is rpm output but I'm using a computer controlled small cap. holley diagram doesn't show any yellow wire connected anywhere. Should i cap it and tuck it away?

and secondly the all white wire. i think its for msd type ignition box, im not using a cd box so should i cap and tuck this too?

thanks for any help

 

I tried looking this up, but couldn't find anything on it either. I see you posted in the Holley forum. Don't worry, Danny is great and I'm sure he or others will reply there quickly. I would suggest you go back and update your thread with what harness you have, wire colors by themselves may make it difficult for Danny to guess which one you're asking about.

 

ok cool thanks. ill wait for a reply on holley forum.

 

if using gm small cap hei (computer controlled) cap and tuck away the yellow and the white wires. you do not need them.

red/white:switched 12v
red: 12v
green: fuel pump 12v.
white: do not need. cap and tuck
yellow: do not need cap and tuck

everything else plugs into a sensor so should be self explanitory
