problems with hks turbo timer harness

[95s14sr]

I have a hks turbo timer, I bought a hks turbo timer harness from enjuku. the plugs match up, but the s14 harness has a extra wire than the hks tt harness. When plugged in the tt comes on but the car will not start.
I called enjuku and they said it is the correct harness for the tt, and they thought it was the start signal wire but couldn't tell me for sure.

has anyone else had this problem that could b of some help?

i had that problem with mine i ended up just hardwiring part of it it seemed i had a plug that fit but one pin was missing but that was two years ago i cant recall the specifics. but it would work the first time and then after would go into some sort of security mode. all this was on a fet turbo timer and harness but also happened when using the apexi stick i have now
