1975 guage with 87 motor Oil pressure sender.

[drophit]

I have a 75 911s with the numeric oil pressure gauge, connected to the 87 3.2 pressure sender. So, i got this part, 91160611100 and went to install it when i noticed the wire that on the 87 3.2 motor was diff and appeared that it would not fit with the part above.

Now i can not find the right wire here on the pelican site. I have already replaced the temp sender unit with a 1975 temp sender, and that connected up fine.

It actually looks like the wire that goes to the temp unit is part of the wire that goes to the press unit.

I am guessing i need the 1975 wiring and wonder if it will just connect up to the 87 motor or will i have to splice. Anyone know the part number for the wire i need? Or can i just wire it up myself?
