I have put an RB26DETT engine on Motec M800 management in my R33 GTS-t. It's been a long term project, but it's nearly there. However, I have forgotten where an eyeletted wire in the starter / alternator loom goes. It comes out of the loom as a heavy gauge single black wire with a brass 6mm ID eyelet tag on it near to the alternator. It looks like it would go under the main fuse box to starter battery plus wire, or maybe it's an earth lead? I have the small eyelet that's the alternator body earth connected to the rear body of the alternator, so I don't think it goes there.... Any ideas please? I am getting no battery positive to the injectors at the moment, it's a car loom issue, not a Motec patch loom issue. Thanks.
