Outer Limits 4x4 Board

Hey guys, I have an aftermarket (speco) oil press gauge. I don't really need it but had to fill the third hole in the pillar pod I bought for a boost gauge. The problem is, where to fit the huge elec sender unit? I found the factory switch type sender for the idiot light, but it's in a C of a spot. Is there another easily accessible port to tap into on a 3L TD?
Cheers

The oil feed line to the turbo, you can come in over the top of the bango bolt fitting If its a series 3 there will already be a oil sender there, you may be able to use a tee piece there, cheers Phill
