I got a paint set from a 2004 Heritage that I am putting on my 2007. The guts from the 07 fuel tank wouldn't work in the 04 tank, as there was no place to mount the fuel gauge sender unit. So I bought the fuel pump/sender assembly from a 2004 Heritage. Ready to slap it in, when I discovered that the plug receptacle on the 2004 top plate is more oval-shaped and has only 3 pins; and the plug on the 07 wiring harness that connects to it is more flat and has 4 pins/wires.

I've got the parts coming for the 04 wiring harness plug, but the problem remains of how to connect the 4 wires on one side to the new 3-wire plug. Anyone been through this before?

Thanks, dta0251

 

I've never seen it but you may be able to compare the service manuals for both to look at the plug pin-outs, etc. to see if you can revise the connections to work for you. The service manuals have the complete wiring diagrams in the back of them.
