fuel relay

So the 88 f250/460 iam trying to fix has no fuel relay. The previous owner got it to run by puting in a low pressure inline pump that he powered of the ignition using only the rear tank. the intank pump had been removed and he was pulling fuel up the tube. I have replaced both intank pump and sending units and now im trying to energize them. The fuel relay has been cut out. I have purchased a new plug and here is my problem. the new plug has a yellow, red, brown and orange/blk wire. I can find a cut yellow, brown and red. but no place to connect the orange blk. all help will be appreciated.

It would depend on the type relay you are putting in.
See images below.

Yes I know that but what kind of fuel pump relay.
The 88 stock type, bottom relay in diagram above or the Bosh type the top relay in the diagram above.

Most with an 88 will install the newer Bosh type like the 1992-1996+ truck use.
