I just got my tune from Tx Speed. Where do I Install this thing? Is it under the hood in the black box or in the truck under the steering wheel. I havent looked Im sure I could figure it out if i looked. thought id ask first. Also after installition Do you have to turn the key on for 20 Sec turn off for 5 mins repeat about 4 times and It should start on the fifth? that is what I tought I read In another article? A little help please. Thanks

the pcm is located on the inside of the hood kinda next to the driver side headlight, in that area. It has a black plastic cover on it that you pop off (I think its in a squareish black plastic box), once you find it it'll be easy. I don't remember for sure how to do the relearn, its been awhile but i do know that you can go to the Nelson Performance website and there are instructions for it there. At least their used to be. Goodluck

There is no relearn procedure just crank it up.

If it is not your original PCM then YES there is a re-learn procedure. But hey. Dont take it from me. Pop that PCM in there. Crank it and see what happens. If it doesnt start you know what you need to do.

Re-learn
