Hello

I need a detailed vacuum diagram for my 1989 Renix 4.0, I know there's plenty on google, but I cannot find a complete one, only partial diagrams, and also I didi not find any vacuum diagram that have the lines going to the tranny (manual transmission)

any help will be truly appreciated.

How's this?

Cruiser’s Renix ECU Connector Refreshing

Many times when other fixes have failed, it becomes necessary to eliminate the ECU to harness connections as a cause. This requires removing the ECU.

Up under the dash, to the right of the steering column is the ECU. It is held in by three 10mm headed bolts to a bracket. It’s most easily removed using a ratcheting wrench but a socket will work.

Once you get the ECU down, unplug the two harness connectors from it. Visually inspect the connectors and pins.

Using a good quality electronics cleaner, liberally spray both of the harness ends and the ECU pin area.

Now, take a small pick or a dental tool and go to the harness connectors. Using the tool, tweak each female receptacle in the harness plugs so they will grasp the ECU pins more tightly.

Plug the harnesses back on to the ECU and reinstall it. I usually only use two of the bolts because the third is a bear.

Thank you both for the help.

One more question, my Renix is a manual and has the vacuum disconnect on the front axle removed, is there any other use for the vacuum lines that go to the transmission? or can those be removed as well, just trying to keep everything clean and simple!

YOu mean the ones to the transfer case? Ditch 'em and plug the vacuum source.

Does anyone know that that little part that connects the vacuum line to the top of the block (front hole) is called? It's that removable almost elbow-type thing but I cannot find it separate from the harness anywhere but it's probably because I got no clue what it is called.
