I want to disconnect the three plug connectors tot he PCM.The plugs have some kinda latch to disconnect them from the PCM but I tried pulling on the latch and and it doesn't seem like it wants to move.Whats the secret? I plan on connecting a Raptor shift light directly to the PCM tach signal and power leads.Thanks.

No secret, just pull, make sure you disconnect the battery ground before removing the pcm connectors. You might have to remove the plastic covers first, i can't remember, but I removed mine before removing the connectors.

Yep, nothing special is needed to unlatch, then the connectors are very easy to pull out.
