Question on tapping into 12v switched wire How many components can be tapped into the same 12v switched wire? like the big pink wire under the dash.
I already have my fuel pump going to the open spade Ignition on the interior fuse block on the drivers side.
Now I need another 12v switched tap in spot for my fuel pressure gauge. What do you suggest?

A fuel pressure gauge won't pull many amps for current - probably less than one amp - so you are likely OK. What does your wiring diagram say is on that pink wire you mentioned? Are they big consumers of juice?

Each of the three user power ports is listed in the manual as being 15A maximum. Each circuit is separate so if you're concerned about too much current draw then you could use the ACCY port for your gauge. The only difference between it and the IGN port (I assume that's the one you used for the fuel pump) is that the ACCY port remains powered after shutting off the ignition for about 10 minutes or until a door is opened - like the radio.
