Remove that switch, remove that rigged up hose, and mount 3 bar to the bracket. You will need 2 screws to do this.
Plug the harness into the TPS and plug the other end into the 3 bar. Run green wire to alky controller.
Install a new hose from port on intake to 3 bar map sensor port. Put a zip tie on each end.. done. I use AC Delco brand 5/32 hose when I do it.
Seeing your car has that switch, means it was a digital dash car originally.
Don't use the 3 pin weather pack plug in the picture as its old and not going anywhere inside the car. So in the end the 2 pin blck plug and the 3 pin black plug in your picture.. you won't use.
Hope this helps
