At the current moment my lt10s is running stock coils without the x box. Which means I'm running on L1, T1, T2 wires off the lt10s. I have ordered the sake bomb garages kit for the mounting bracket, 4x ign-1a coils with harness and they are on the way.

my questions are:

1. How do i know if my lt10s is set up for 3 wire or 4 wire ignition? Currently they are spliced into the ecu harness and i do still have the L2 wire coming off the lt10s just hanging there not attached to anything (Although ive heard that the L2 wire should be spliced into the leading along with the L1 wire, not sure if true its not).

2. I know the new harness will delete the igniter and i will have an option to run 3 coils or 4 coils wiring by simply cutting the jumper wire. Is there an actual benefit to run a 4 wire setup?

3. Do i need to configure the lt10s to run a 4 wire setup instead of a 3 wire setup?

4. I want to run the ignition wires directly from the lt10s to new harness and there for will have to extend the L1, L2, T1, T2 wires to the drivers side, maybe 5 ft each wire. What gauge wire and will i need to run shielded wires?

Thank you.
