Default LED bulb replacement

Is there a light bulb chart/ reference for which lightbulb 1156/57 goes in each lens for the 944? I want to go 100% LED and need the info.
I got rid of the front turnsignal housings so don't need those.

Thanks for the chart.
I have the 4 sidemarker LEDs (5007)
and license plate LEDS (3893)
Big question... Are all the rears 7506/1156 single pole/filament? or do the turnsignals have 7528/1157 (double pole)

Ok. I opened up my spare driver' side rear tailight housing and all are Single pole. That's good neews as I have 10 spare 68-smd LEDS...

Question is, why is the red lens under the clear back-up lens empty from the factory?

You can change that if you want.

I did here are the pictures of the car I did and the car I did not do. You can compare how different the lighting is.

Default gauge bulb sizes 85.5

Anybody know what size/base type bulbs go in the gauges so I can order them now and convert them all to LED when I do the Tach mod?

Thanks SMO, I just bought a 4 pk deal off tha bay they are 168 type 1-smd bright white. Since I converted my car to V8 power, I will mod the spare one up to be the warning (!) indicator wired directly from the GM PCM. Thanks again for the tip.

Only one of the warning lights in that pic have LED replacements installed. White, single led I think. I still have a few laying around too. The warning lights are a different connection than the back lighting btw.

From memory I think the ! light is the only one replaced in that pic. And for reference here is a pic of the back of a late model gauge pod. The red circles are the warning lights and the three yellow circles on the bottom are for the backlighting. If the back lighting is dim it could also be the metallic reflector on the housing has chipped away. I dont' have a pic of that since mine was in decent shape.

Good info, thanks! I am looking in to doing this myself. You've saved me the trouble of searching for the right ones.

Did you use the regular or high power bulbs?

The bulbs circled can be replaced with those LED you have listed with direct links? They are drop in replacements I don't need to solder anything? Are they brighter than stock?

So that ! Warning light is T1.5?
Can the ! Warning socket be modded to fit the brighter 168 bulb? (I have extra)
The GM PCM Check Engine Light only needs one Light, so all the other indicators I will pull out as they are not needed for the V8 swap.
I have self adhesive relector tape that I will use if the housing is worn.
