Hello everyone. I'm in need of some help and I can't seem to find what I'm looking for online anywhere. I have a 1985 F150 EFI with dual tanks. My valve started leaking and needed replaced. This item is no longer made so I found a used one on ebay. It's a 6 port valve that matched my hoses exactly. The problem is that the connector has wires that are all different colors than the one I removed. It looks like a OEM valve, but must be of a different year vehicle than mine. I knew my connector was in bad condition and this one came with a new connector. My original connector has Y/LG, Y, DB/Y, Red and Brown. The replacement I bought has Or, Green, Green/Red, Brown/Or and Red/Y. Anyone know how I should match these wires up?
This is the original connector.
This is the replacement unit.

It did not come with a wiring diagram because it was a used part. They sell for about $300 on ebay in NOS. But I found this really good condition used one for $75 and it came with a connector. It doesn't have a part number listed on the part, but did say "FORD" on the side. So I don't believe it's an aftermarket replacement unit. Also the fuel connectors all were just like the factory unit, not made for rubber fuel lines. I have found the diagram of my factory connector, but I can't find a diagram showing the colors of the valve that I bought. The diagram above doesn't have the same color wires either. If anyone knows what year of truck might use these colors, please let me know.

I checked the truck wiring up to 89, and no change in color coding to the valve.
does not look like the electric valve was used after 89', 90 & 91 drawings do not show an electric valve for Gas, and the Diesel valve in 90 has the same color codes as the gas valve.
If it is a ford part, there should have been a number on it somewhere.
Your Red & Brown are candidates for motor direction - one polarity it selects rear, swap the polarity and it selects the front.
The other 3 wires are gage selection.
Your new 4th wire, Green, is most likely the common Gage wire (old -Y/W)
You can prove this by measuring continuity on the other 2 wires in respect to the 4th wire, while applying power to the Red & Brown one polarity, then the other.
2 of these 3 wires should be connected now internally and the continuity can be checked.

I was wrong. The original valve did not have a number on it. This replacement unit does say Ford, but also has a number on it. I have googled it and it gets zero hits. The number says, "E7TB-9F271-AA". Does this mean anything to anyone?
Thanks,
Charles
