Resolved '90 Broken connector at firewall, which wires to which?

[Gabe92RTTT]

Hey folks,

This connector is long gone and the 4 wires are not 1:1 in terms of color on this '90. It starts up and runs but I have no clue what sensors these wires go to under the intake at the moment. The spade connectors are temporary until I can be sure and then get a proper connector. The car starts and idles fine but the tach is reading low and I doubt they are wired correctly. Any help is appreciated!

Harness/firewall side:
Green w/ Black stripe and red tipping
Green w/ White stripe and red tipping
Green w/ Red stripe and red tipping
Green w/ red tipping

Sensor/engine side:
Green w/ Red stripe
Green w/ White stripe
Green w/Black stripe
Black

Throttle position sensor and idle position switch. A-55 in the below diagram. The wire for the idle switch on the sensor side harness is a black wire.

The diagram shows the positions of the wires in the back side of the engine harness connector.

Here’s pictures of the wires on the connector for the sensor side.
