I need to know the wiring diagram for a 2002 chevy tahoe tail light please and thank you

Park, Tail and Marker Lamps
The park, tail and marker lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The PARK LPS 30 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the park lamp relay switch contacts and the park lamp coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the park lamps are turned on the BCM energizes the park lamp relay. Current flow is from the park lamp relay to the FR PRK 10 A fuse, RR PRK 10 A fuse, LR PRK 10 A fuse, and the TRL PRK 15 A fuse, and to their respective park and marker lamps. The front park and marker lamps are grounded at G100. The rear park and marker lamps are grounded at G401. The license lamps are grounded at G401. If the headlight switch is left in the ON position, the inadvertent power control feature will turn off the park, tail and marker lamps approximately 10 minutes after the ignition switch is turned to the OFF position. If the driver places the headlight switch in the ON position after the ignition switch has been turned OFF, or if the ignition switch is in the ACCY position, the park, tail and marker lamps will remain on until turned off or the battery runs dead.
The CTSY LMP 15 A fuse in the engine wiring harness junction block supplies battery positive voltage to both the inadvertent power relay switch contacts and the inadvertent power relay coil circuit. The body control module (BCM) provides a ground or control circuit to the park lamp relay coil circuit. When the driver presses the cargo lamp switch, the BCM energizes the inadvertent power relay. Current flow is from the inadvertent power relay to the cargo lamps. The cargo lamps are grounded at G203.

99 GMC Sierra headlights & running lights won't work!

Headlights Circuit Description
The headlights are controlled by the body control module (BCM) via the AHL Relay when the headlamp and panel dimmer switch is the AUTO position. When in the AUTO mode, the BCM receives a signal, (voltage) from the ambient light sensor, based on the voltage of the signal of n the sensor the BCM turns the day time running lamp (DRL) lights OFF and the headlights ON. The headlights can also be turned on by placing the headlamp and panel dimmer switch in the head position.
The relay coil is fed by the headlamp and panel dimmer switch or the BCM and the battery B+ buss bar in the underhood bussed electrical center (UBEC). The BCM supplies current to the relay based on the input from the ambient light sensor via CKT 352.
The relay output feeds the LT HDLP and RT HDLP fuses to supply current to the low and high beam lamps on CKT 1340 and CKT 1240. The ground for both the low and high beam lamps is supplied via CKT 524 and CKT 525 to the dimmer switch. The dimmer switch uses CKT 1850 for a ground to G203.
Some circuits are monitored by the BCM, and upon failure may set a DTC.
Park/Side Marker and Tail Lamps
The park/side marker and tail lamps are split between the following 4 fuses:
?€¢
The FR PRK


?€¢
The LR PRK


?€¢
The RR PRK


?€¢
The TRL PRK

These fuses receive voltage from the park lamp relay. When the headlamp and panel dimmer switch is in the auto position, the body control module (BCM) controls the relay by grounding CKT 1080 based on the input of the ambient light sensor. The park LPS fuse supplies battery positive voltage (B+) to the relay at all times.
When the headlamp and panel dimmer switch is in the PARK position, the relay is by passed through the INT PRK fuse. Current flows from the PARK LPS fuse through the headlamp and panel dimmer switch to the INT PRK fuse in order to feed the following fuses:
?€¢
The FR PRK


?€¢
The LR PRK


?€¢
The RR PRK


?€¢
The TRL PRK

The license plate new bulbs fail to illuminate an the lift gate locks whenever closed...why?

This answer comes from BlazerForum.com (link is below) for a 2002 Trailblazer:

"It will be a 10a fuse in the under hood fuse box, labeled TRL PRK. If you have towed a trailer lately, and the fuse does not blow when you replace it, I would check the trailer that you used. If you have not towed a trailer, I would check the trailer wiring under the LR or the truck, to make sure none of that is shorting out. Good luck, Korey."

Have a 2002 Chevy Malibu LS with Cooper Lifeliner 215/60R15 tires. The door label is missing. What are the recommended rear and front to4ie pressures?

the door tag says 30 PSI, with your tires i would suggest about 32 or 33 psi because they have a very soft sidewall.

Change lisence plate lights

Look where the wires go to the lights underneath. Grab the white rubber piece that goes into the light housing and twist 1/4 turn. Then pull. The bulb just pushes into its terminal in the white rubber.
