ok i just got a used one and i know what the black,white,red and yellow wires are for. but what are the two sets of small red and blue wires for? also what do you guys have your yellow wires hooked up to? thanks.....

 

anyone?????

 

The small wires are for 4 and 6 cyclinder applications.

 

thanks for the reply

 

if you cut the loops it's for 4cyl or LS1 use.

leave them connected 8 cyl use LT1 application.
