I know this has been discussed before, but the search function (even with google) is not finding me the answer that I need.

I took all my OD components from my parts 1800E, so I have the original relay, indicator light, and stalk switch. I mostly wired it up using Phil's diagram over at VClassics, but am stuck at two points.

1) I have the correct hree-prong 1800E OD relay, but I'm not sure what hooks to what for it to function correctly. I did make a few color-code marks on the relay before I removed it, but it's not helping me much since I'm not working with the original wiring harness. The wire colors *were* Yellow (I think to the switch) Black (unsure, probably the OD itself) and brown (unsure, probably power from the fusebox). I'm assuming that it's grounded to the body of the car...

2) I'm not clear on how to wire up the OD indicator light. I already have the top connector (off position) of the stalk switch wired to the fused side of #2. I'm guessing that the "on" positon connector goes to the OD indicator light and then on through the firewall to the relay. If correct, this would explain why you can switch on the indicator light with the stalk switch, even if you are not in 4th gear. If not, then I'm lost and need some direction here.

So mainly, I just need to know what the numerical codes on the bottom of the relay mean.

Thanks for any information.
