Where do I install the senders for aftermarket gauges?

Oil pressure and water temperature gauges?

[Kris]

I put in a mechanical oil pressure gauge and just tee'd off the existing port for the electrical one and kept my electric one as well, that way the one in the cluster still works and I have the mechanical under the dash.
For the h2o, that may be difficult if you want to keep the original one working. If you dont then the sender is on the front of the intake manifold on the drivers side. Just replace the sender and route the wire.
