My car ran perfect before the conversion with a standard TTFS tune.

All of my wiring seems to be okay (tested with a volt meter and datalog shows all sensors to be working). Car runs perfectly smooth, starts fine cold/warm, idles fine, accelerates fine (but does so VERY slowly). I originally tried running the car without moving the fuel pump relay pin from X60002 Pin 11 -> X60004 Pin 10, and today switched the pin over to the empty slot in X60004 with no noticeable change (runs almost the same, maybe a little more power). Here are some more details which may help:

-Stock US cams (not-CSL)
-Jun '01 build vert
-6MT
-No flap
-Green fuel pump relay (came this way from factory... pin locations were verified today)
-3 error codes: 6, 124, 130

I am waiting for a reply from TTFS but maybe someone on here can help.

*PS thanks to the OPs for all the info it made the wiring conversion very straightforward.
TTFS sent a revision to the tune and that fixed the problem. Not sure what the tune parameters were or if the car was in limp mode with no indication.

As for the conversion the car feels awesome with the new MAP rail setup and the growl/ power is awesome at WOT. Very pleased with the conversion so far!

Default Re: Comprehensive CSL Intake Thread

The wiring DIYs show replacing the wire in Pin 17 of x60003 with the ground from the MAP sensor. What does that wire originally ground? If anyone has a full MSS54HP wiring diagram, I guess that would be helpful and answer my question. I couldn't find one by searching.

I originally wired the ground to Pin 16 which was suggested in another thread. I have had a sub 3000rpm hesitation which I have been chasing and a cold start, rough running problem. If I unplug the MAP sensor, the car seems to behave better. I was chasing VANOS and TPS issues, but the VANOS checks out now, as does TPS. So, on to the MAP and associated wiring/tuning.

What is "black connector cluster" as listed here? Is it the 8-pin guy on the driver side wall of the box next to the 4-way split of the hot wire? (It comes from the engine harness.)

There's an empty pin on the 3-pin alternator plug itself, but it's not #2, plus I assume if that was where this was going it'd just say that connector by name...

Use the pin out instructions.

All you are doing is punching pins in or T tapping them.

Ignore all the garbel speak.

That's what I'm confused by. Pins out of pin 2 of something I'm not understanding (as opposed to "X60004" or "MAF harness, which I can identify). What is "black connector cluster?"

Should say "black connector of cluster" - as in literally the black connector that plugs into the instrument cluster (there's a black one and a white one)

Found another... same pin being used as power and ground on different things? Typo? Is there a reason we aren't just following the CSL pins and use X60003 pin 25 for IAT's ground?

(I'd just use the MAF but I don't actually have that harness anymore. Actually I'm just going to plug things in wherever Terra tells me to anyway.)

Yeah that seems like a typo. I *think* the ground is supposed to be pin 15, but I have to double check that.

You can just follow the CSL pins, but those pins are used for ground for a lot of things, so it adds some work compared to just reusing an existing ground or running a wire to one of the unused grounds

25 - (OE location is 22 and 25 for IAT) had an existing ground in it so I ended up hacking into that one, which ended up being far messier than I had hoped since I had a nice perfect length pinned end ready to go in. I was too lazy to run back inside and up to the computer to check the diagrams to see if any other pins (ie 15 that you mention) might also be grounds.

Speaking of pins in use, two of the three flap motor pins were occupied too. I left it alone and will re-visit that when I actually get a snorkel.

Those pins are originally used for the MAF. CSL repurposes them for the flap sensor.
