I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

The door speakers are 6", not sure about the ones in the rear deck.

Constant 12V+ Orange
Switched 12V+ Yellow
Ground Black
Illumination Gray
Dimmer Brown

Front Speakers 6 1/2" Doors
Left Front (+) Tan
Left Front (-) Gray
Right Front (+) Light Green
Right Front (-) Dark Green

Rear Speakers 6 1/2" Rear Deck
Left Rear (+) Brown
Left Rear (-) Yellow
Right Rear (+) Dark Blue
Right Rear (-) Light Blue

They relay is on the horn itself. That's why a replacement horn is a dealer only item that's $85. You may need to do some creative wiring with a generic relay. Good luck.

Here are the wire colors and what they do in the system. Please rate my help.

Hello DTC P0341 & P0133 very common saturn Codes.You need to check condition of Plugs & wires,If not New Replace All Plugs & Wires,also I would replace the #1#4 Coil for the P0341.For the P0133 Reaplce your front O2 sensor with an OEM sensor,not an aftermarket.

1. Test the AC voltage output from the Crankshaft Position (CKP) sensor while cranking at a normal speed. It should produce at least 250 millivolts.

2. Retest the voltage at the Powertrain Control Module (PCM) on the Yellow wire in terminal D13 and the Purple wire in terminal D14.

let me know please thanx i hope it fix

The best place is the rear of the radio where there should either be an orange antena wire or a blue remote wire comming from the radio.
