Default LS1 foxbody wiring?

Hey guys, I am finally wrapping up my ls/t56 swap into a 1991 coupe fox body and was running into a few issues with the wiring. I have read pages and pages of posts throughout this forum and was trying to figure out a definite answer as to how everyone is wiring their ignition/starter? I am using a Speartech wiring harness for the engine as well. Anyways, here is how I've done it so far: I am currently running a large 2G wire from the + side of the battery to the left side of the ford starter solenoid which will also connect to the bundle of wires powering the headlights/alternator/etc. I have left the small blue/red ignition wire alone that runs to the small post on top of the ford solenoid. The large post on the right side of the ford solenoid runs to the large battery post on the GM starter. From there I am running a jumper wire from the battery cable on the starter to the small post on the starter. Do I have to make any modification to the NSS or Clutch Interlock Switch for this to work? Any help is greatly appreciated! Here is a link I followed for how summit racing runs a remote solenoid. I used my ford solenoid as my "remote solenoid".

(bump) nobody out there has done the wiring on an ls/foxbody swap that could point me in the right direction?

I removed all of the Ford stuff under the hood. The mess on the starter solenoid looks bad. I used a positive stand off to connect all of the positive wires to. The red/lt blue went to the solenoid, the factory neutral switch on the clutch was used.

I think you should be good to go. If you didn't mess with the NSS or the clutch switch and they are working, then your ignition will trigger the solenoid when you go to start it.
