Here is a writeup about the install I saw a while back when I considered going this route for tuning. It is from HTC.
>>>>>This is how to wire it up on an 04'<<<<<
Red wire t-taps to (C1P29) Solid Red wire
Black wire t-taps to (C2P27) Blue w/ Green stripe MAP Sensor Ground (Middle wire of MAP Sensor)
Cut MAP Sensor Signal Wire about 6" before PCM. This wire is Purple w/ Black Stripe going to C2
Violet wire splices to (C2P23 Purple w/ Black Stripe) cut end of MAP wire on the PCM side*
Yellow wire and Green wire go together and splice into cut end of MAP wire on the MAP Sensor side Purple w/ Black Stripe wire
Yellow w/ Black Stripe wire t-taps to tach signal off #8 Injector. The wire closest to the red clip*
Yellow w/Green Stripe wire is not used (not in diagram but is on the PSC1-003)

Red wire t-taps to (C1P29) Red w/ White Stripe*
Black wire t-taps to (C2P27) Black w/ Light Brown Stripe MAP Sensor Ground (Middle wire of MAP Sensor)
Cut MAP Sensor Signal Wire about 6" from PCM. This wire is Green w/ Red Stripe going to C2
Violet wire splices to (C2P23 Green w/ Red Stripe) cut end of MAP wire on the PCM side

Jason, good stuff, I'm wired as istated with one exception. I'm tapped into the GY/LB wire at the PCM and not at the injector itself. I'll change this today and see if it fixes the rpm readout. Thanks,

I was wired to the GY/LB wire at the PCM and I moved it to the injector. I didn't expect any change and there wasn't any. Called Split Second and got a call back from Mark and got it sorted out. This is easy if someone tells you, but no where does it tell you that changing the screen doesn't do anything until you update the unit (they call it a ECM). This is done using a icon in the upper left corner on the map page. So this is the two additional pieces of information needed to make this thing work.
1. After install, connect to the ECM and download the map. Modify the map to all 10's.
2. Upload the map back to the ECM, this will resolve the TB warning icon on the dash.
3. Select the 1 cylinder/ 4 stroke if taking the rpm trigger from an injector. And upload to the ECM. These two step can be done together. The key being upload the data you have selected or it won't be installed to the ECM.
This is easy stuff, but if you don't know, you won't get it..
Anyone who needs help in the future feel free to contact me.
Good luck
