Anyone had an electrical problem stemming from the ignition and tail light/ window harnesses cluster works intermittently and windows tail lights brake lights and reverse lights all kill engine once you finally do get it running. It's a 91 loredo 4.5 inch rubicon express built d30 up front welded 35 in the rear. Sye done correctly and it's a beast just can't pinpoint this wiring nightmare. Ive replaced all ground straps and positive terminal on the battery. Cleaned the kick panel fuse box harnesses and added dielectric grease. Bypassed the NSS. And still can hardly ever get a response from the cluster. And when I do I have to jump the started. Had the started tested three times checked out fine. Isolated the electrical systems and found that there is a short somewhere along the lines of ignition but can not pin point one particular thing related to all effected conditions. Ready to loose my mind on this thing. Begging for help and if none can be provided willing to sell for $2000 or trade for a 4 cyl daily commuter until I can build another rig.

 

Here's a few pictures.

 

First, why and how was your NSS bypassed. Second, have you investigated your ignition switch (located on the steering column, near the pedals)?
