So, Key ignition assembly has 5 wires (where u put the key and turn it to start... u know...) it has 5 wires comming out of it, i wired all as they were but i fried the whole Black/Red wire all the way to the Fuse Box in the engine bay.... had to rerun it

So i cut the Black/Red wire and rerouted it directly to the fuse box in the engine bay...

I wired it just like the pic below, new line comes from key assembly, splits to SMJ and then follows the the Fuse Box on Eng. Bay. but it wont start!!! if i connect the old fried line to the new one it starts just fine...

Without the old fried line connected the Top left relay on the fuse box starts clicking every 1 sec.... if i connect the old fried line it doesnt click and car turns on just fine... soooo im missing that Purple line... where is it....

So i saw the Diagram when i got home and i found that OK Red line is Good i did it fine, but the purple line..... Wheres that split??? its not below the dashboard.... and after that the harness goes under its cover all the way to the Fuse box.... WHERES THAT SPLIT?!?!

Please help i dont wanna destroy my whole harness cover just to find that split... anyone knows where is it?

Edit1: HMmm ignition coil has that same wire... but it goes to the Maf/Inyectors harness..... How the H does that B/R Wire connect to the one im tracking??? According to the ECCS Wiring Diagram the Wire comes to Fuse, Splits to SMJ, Splits to Ignition Coil (Wonder how, cause i mean that B/R wire goes to the Firewall near the ECU then i lost it there, maybe splits to the ECU but i dont know how it joins up with the Fuse Box etc.... :S) and the to the Terminal 34 on ECU.... So where does it split to the Ign Coil? Help? if not im gonna dig that mofoca tomorrow...

Oh well, did it

Info:

The ignition main cable is Black/Red, starts at the Key assembly (where u turn the key etc.... u know) goes below the dashboard, connects on a plug and keeps going, splits in the SMJ box, same cable goes to it and keeps going to the engine bay by the harness, goes all the way to the fuse box near the battery tray, goes to a Fuse 10 AMP, it splits to the Ignition coil SOMEWHERE between the Relay box on the driver side and the battery tray (insde the harness that goes near the radiator, somewhere near there it splits in two Black/Red Cables) near the grounds on the passenger side Grounds that screw near the Headlight, around there u should see Both Black/Red cables inside the harness, the new split goes to the ECU and also to the ignition following the inyector harness etc all the way with the maf etc....

Done... wired it, my frying line was the White line on the key assembly, it was open circuited in the Relay box, the relay was fried so i unplugged, didnt lose any accesories or anything so i keep it disconnected ftw :D
