Im running my wire now and i came to a bump on the road. I have a 2000 LS1 with auto tranny in a 89 camaro. Now, on the C105 LS1 connector, C100 plug there are two wires for the PNK HOT IGN wire. Do i just use my one PNK IGN wire from the camaro and split it??

 

i used a seperate fues box i got out of a junk yard car and took my main wires from the key cylinder that go through the firewall and hooked them up to the fuse box that i mounted where the battery/old aircleaner went i then hooked up each seperate ignition and power source on a 10-15 amp fuse , if you want to hook them up togather it shouldnt be a problem just put them on a 15 amp fuse . they just power up injector and coil banks 1 and 2 i believe

 

Yep, you need to put ALL of the PNK wires together. There are 5 to be exact... 2 on C100, 2 on C101, and 1 on C105. If they arent all connected then the engine will not start.

C105 carries the voltage and it needs to be distributed the the other 4. You need to put a 15 amp fuse between C105 and the other 4. You can do this by going to Auto Zone or any similar place, go into their wiring department and buying an inline fuse carrier. Solder the 4 together and solder then to the one end of the inline fuse carrier and solder the one from C105 to the other end. The in line fuse can double as a theft deterent... if you remove the fuse from the in line carrier the car will not start.

 

I thought you needed to use the TBI injector wires to the LS1 for the fuel and spark. those dont need to be tied together cause they have there own fuse. Its the other 2 that i have a question about. I just tied them both together and used my ING Switch PINK wire coming out of the 89 C100. I figure if the PNK wire was going to the ING on the distributor that is should hold it self.

 

GM kept them apart for a reason. basic wiring safety.
each one of thoes wires should have a current limit on it (aka a fuse)

for the Ignition/injector power, use the old injector power feeds.. this way theres one fuse for each bank... 15A in each if memory is correct (check me.)

for the other wires, like MAF power, O2 power, trans power, ect..... use the proper fuse for each. dont just connect them together.

 

The only fuse I had to put in was the 20A one for MAF/reverse lockout (6 spd). For the other power inputs I ran power from my fuse block using my existing fuses with the exception of using 15A for INJ1 and INJ2 instead of the 10A. Im pretty sure I used the somewhat heavy guage pink ign wire for my MAF power
