What Are These Ports for LSA??

[joeko23]

I have a pullout ZL1 LSA and can’t figure out what these ports are for and what I should do with them. Any help is greatly appreciated!!

the second one is the evap system port PSI harness eliminates it. from their instructions:
3. LSA engines utilized Evaporative and CCP features for emissions control. This
harness does not include these provisions. Evaporative and CCP are not necessary
for engine operation. ECM reprogramming may be necessary to avoid storing a
Diagnostic Trouble Code (DTC) for absence of emissions equipment.

First one is believe is another vacuum port which can be capped

So both ports can be capped? What should I cap them with? A link would be great. Want to use the right cap for the job

I bought an evap solenoid cover on eBay. A regular plastic vacuum cap will work fine on the other. Do you have power brakes?

I think this is it:

you can use a simple vacuum cap on the nipple style

Thanks for the links guys. Yes I will have power brakes using vacuum which is a different port that I figured out.
