Trying to make my 80mm work, but need pinout data for 03 CL55 and 04 CL600. Think it might be different than the 1-4, 5-6 swap. Thanks

anyone?

How do I change the pins? Want to change them on part that plugs into throttle body, but there is a plastic part on top. Not sure if I have to (how to) take that off or can I get to the pins on the backside of the wiring harness?

You can't change them at the TB. It is epoxied in. Change them on the end that plugs into the 10" long pigtail that is attached to the TB. Very hard to get the pins to release. When you plug them back together make sure all of the pins insert into each other correctly. One of mine pushed out and when I started the car it wouldn't run. Quickly realized my mistake and all was good.

That's what I meant.... how do you get pins to release?

i believe that we ended up swapping the following pins on my 80mm TB
1-4
2-3

jicl55

Yeah, someone swapped wrong ones and I want to swap the right ones but never pulled pins before and just don't want to damage them. How do I release them?

special pin removal tools...

jicl55

thats what i was afraid of... do you know the tool?

Hazet (and doubtless many others) offers the tool - it's the blue-handled tool on the left in this picture. I used it when I installed my Renntech ELM, and I also confirmed it works on the TB pins (upcoming project). I got the tool number from the Renntech ELM installation instructions, which are available at Renntech's website.

What are we trying to match here? If we all wanted it to match, it would appear to be a 2-3, 5-6 swap. am i missing something? Are we not trying to match?

The 80MM TB opens in the opposite direction. That is why #1 & #4 need to be switched. Depending on the model of 80MM TB you have, either #5 & #6 or #2 &#3 need to be swapped.

jicl55

I'm thinking the 1-4, 5-6 swap was the right one. Anyone care to check that and figure this out for me?

It depends on which TB you have. There are a few different 80MM TB's.

Your cl55 wiring diagram confirms it is like the E55 in the chart I posted, #1 & #4 are motor +/-, and #5 & #6 are potentiometer output.

However the cl600 wiring diagram indicates the motor + is on #6 and motor - is on #1 so it looks like you will have to switch #1 & #6 to get the motor to work correctly. This is only true if your cl600 TB opens opposite to the one on your cl55. Check this first. Get the motor opening the TB correctly first. If this is true you may also have to switch #2 & #3 with #4 &#5 to get the output and inputs corrected.

The main reason for the switch is because the + / - and potentiometer output was different from the 74MM to 80MM TB.

Hope this helps. Be sure the pins push all the way in. When you connect the two connectors, look and make sure the pin did not push back out of the back of the connector.

CL600 throttle body does operate in the opposite direction.... kinda looks like I have to change all sorts of wiring.... I saw the M- and M+ being on #1 and #6.... thought it was kind of strange. Looks like Blue and Black are the power on the CL55, but yellow and black on the CL600? Thought it was weird. Just want to make sure I'm looking at it right.....

jicl55

First thing I noticed in CL55 is 1,2,3,4 are inputs, 5,6 output.
CL600 shows 1,4,5,6 are inputs, 2,3 outputs....

I need someone smarter than myself to figure this out for me.

jicl55

I think I had the wrong CL600 wiring diagram..... this one makes a lot more sense. Compared to my CL55, looks like 1-4, 2-3 are the right changes. Feed back?

Correct
