s13 what do these connectors do.

[bogan]

hay everyone just checking what these plugs do. just wiring up the 1j and

just checking if i will need these connected to anything or not.

comes out of the alternator relay in relay box.





just need to know what the one on the left does?


positive or negative im assuming its going to be positive?


running a chasebays wiring harness cant seem to find the plug to suit this anyone have an idea what it might be for or where i might find the plug im looking for

The First pic goes to the alternator. It plugs into the lower trans. harness under the fusebox.

In the second pic the narrow two-pin connector on the right goes to the brake master resovoir for the low brake fluid lamp. The two-pin connector on the left goes to the vacuum solenoid for the air injection pump. There should be another one-pin connector in that loom that goes to the A/C compressor as well.

The bottom pic is the main power feed to the fuseboxes, those just go to the battery.

EDIT: DAMNIT! You added another pic on me!

Cheers mate in the chasebays pic I uploaded would you know where to find that brown plugs friend. I dont have the sr20 ecu harness could that plug into somewhere on there and that's why I can't find it?. Could u also tell me what the fat white wire does coming off the alternator relay. Cause im using a 1j I dont think ill be able to use it anyway but I thought id just check

That brown plug goes to the underdash harness by the ECU. On SOHC cars that connector is white, on DOHC cars it's brown.

Still cant see it am I bind?

It's that long white connector!!!



Is your car RHD? Looks original too...

If your car is a silvia/180sx it's not quite the same.

Yeah rhd umm yeah small problem the plug on the harness is exactly the same as the chasebays plug? Im starting to get it im missing whatever connects to that white plug on the car so thats why I cant find a connector to suit
