Looks like the wiring is similar, I'll reference what I have below. Keep in mind yours may be different pin numbers. You need to have the ECU tied to chassis ground. There are two points that have heavier gauge wires, pin 11 and 12 that need to be tied to chassis. The sensor grounds are tied...

I have a CJ7 that I did a head swapp off of a 91 XJ. During the harness swapp I couldn't figure what was what (haynes manual really suck). So I ohmed out each wire / color code / pin #, yeah no life here. Different ECU's but Jeep kinda followed the same sensor style setup . The sensor grounds...

For obvious reasons I'm doing a 4.0 MPI head conversion on my 1977 CJ7. The doner was from a 1991 XJ. The fuel rail supply and return are 5/16 tubing from the 4.0. The stock fuel sender is 5/16 supply and 1/4 return. Has anyone out there done this conversion on a CJ. My concern is too much...
