I need to know what the 4 wires coming from the distributor on a 1987 sentra are for. They are Red, Green, Black (I'm guessing a ground) and White. The Chilton book we have only shows two wires coming from it and doesn't show colors.

Thanks

I hate Chiltons books. I can get you a wiring diagram from my HAYNES book that might help you out. And while im at it...let me know if you need any other diagrams.

I believe they had two distrubutors in 87 one for the i and one for the s engines so besure to get the right diagram for the engine you have. Why do you need to know what they are for?

In my modified 87 sentra us version:
There is a magnetic module inside the dist with 3 terminals labeled like this:
B Ignition 12V+
C Coil (negative terminal)
T Tach signal
And there is a wire that comes from a ground conector from the dist body

There is another module (optical) that came with the electronically 'aided' (impaired) carburator
I don't know about that one, it gets a crankshaft position signal too...

We need the wiring for the optical one. We are using a modified 87 Nissan Sentra dist. on an 87 Celica with a 92 MR2 engine to get a hall effect for my haltech setup.

I need to know which wires are which at the distributor. I need to know what the red white black and green wires AT the distributor are labeled as...i.e. which one is the trigger wire, which is hot, etc. etc. Thanks.

Note: This Nissan distributor is being used on a Toyota Celica with a 3SGTE (MR2 Turbo) engine swap and a Haltech EMS. This is being done to creat a hall effect since my stock dizzy isn't set up for that. This is why I need to know which wires AT the Nissan dissy are which. We have wiring diagrams for the Nissan but none of them show the wiring color codes. Thanks.
