Wiring information

[N1ceDrgn]

I am wrapping up a CA18 install and have an ignition problem. I have managed to find a good wiring diagram thanks to you here. The only drawback is I can't find an accurate / complete wiring diagram for a '93 240SX SE w/KA24DE. I am having an ignition problem, the harness's are getting grounded out some where from the positive terminal connector back down the harness and I don't have the information to check one against another. I have gotten this far by myself and personal knowledge. However looking for/ finding wiring help has not been an easy thing or something I am able to do. I also would prefer not to leave the car with a shop for two weeks so it can sit for a week and a half and get maybe a couple days work done to it, (I just have a hard time with that.. anyone else?). If it comes to it, I could take it to a shop as a last resort but even then I have no ideas where I could take it. I only know of a couple of shops in the area, (San Diego), that might have a clue/ may be able to do the job. So, if anyone has any ideas/ knows of a reputable shop/ knows where I can find the wiring diagram (suggestions), I would be grateful and it would be appreciated. (Sorry about the lengthy post).
