Hi,

did somebody ever made a list of all connectors,grommets,rubbers,etc... needed for a 2.7 cis 1976 system,perhaps include pictures?
would be a big help.

What are you actually after? Rubber components like intake runner to air box? Gaskets like intake runner to head? Electrical components like the wiring connector to the WUR?

Love to help but connectors, grommets, rubbers, etc is pretty vague.

cheers,
Frank

If you're looking for electrical, contact user Timmy2 here on Pelican - He makes replacement wire harnesses and I think has a source for the electrical connectors.

I use this to typically ID part numbers (click on the k jetronic pages and it brings up the corresponding numbered parts list) and then purchase from our host:

…well that didn’t work - clearly they block out any mention / link to a competitor. Will send you a pm

[jimmyjimmy]

Iīm talking about the electrical connections.
I have a saab 900 1987 turbo convertible with a k- jetronic system (cis)and I think there are the same connectors used, or at least part of them.
So I'd like to know all the connectors used in the cis from a 76 911.

thanks

I think the Porsche parts diagrams only list complete harness chunks.

PM user Timmy2 - he can probably get you a list and/or provide parts.

[timmy2]

Likely timer junior or JPT type. Search Mouser or Digikey for them.
Porsche never sold them separately. (Connectors)
Post some photos of what you are looking for.

[jimmyjimmy]

yes JPT thatīs certainly one of those connectors ,thank you but are there others used?

[jimmyjimmy]

and are they only made in one dimension?

[timmy2]

Post photos of what you are after.
There are other connectors like the 14 pin for the fuse panel and the CDI 3 pin connector.
Most everything else are crimp on terminals for the engine harness.
All JPT connectors are basically the same. Just the number of terminals change.

[jimmyjimmy]

Well , I figured out that the jpt connector is missing for the air valve ( brown /brownblack) wire.Wires are brittle too.I'll have to replace and put a new connector on .I'm wondering if I should look at polarity or doesn't it matter how I solder the wires?

For the motorcompartement blower motor I think the relay is missing.Ther's a yellow wire coming from underneath the 14 sprong connector but it is cut off just a few inches after a black kind of connector which doesn't seem to be able to open.I think that's the wire coming from the microswitch near the handbrake,but I'm not sure.This one should go to the relay?
From the 14 sprong connector there's a redwhite wire going directly to the blower.Normally this one should be going to the relay first I think.
Any thoughts?

[jimmyjimmy]

Here's the yellow wire .Should this one be going to the blower relay?
Where is this relay normally situated? I only have one on the electrical board and that's for the wur I think.
The second fuse is also misssing...
The brown black one is the one from fuelpump to air meter I think

[timmy2]

Yes, the yellow wire that is frayed normally comes from the fan relay circuit. I think that one is direct to the switch at the hand brake. The other one from the switch goes to the relay base.
Looks like the round 5 pin relay base has been deleted from the fuse panel board.

Yes, the brown/black is the Fuel pump air flow safety switch connector.

[jimmyjimmy]

Thank you Dennis,

does the Air valve have a positive and negative connection or isn't polarity important?

Is there supposed to be a microswitch near the throttle body? Mine doesn't have one.

[timmy2]

You should have the ground on the right and the brown/black on the left when the connector is installed on the car. Looking at the car from the bumper.
No microswitch on the TB shaft until Lambda system was added in 1980.

Thanks again Dennis,you've been a big help.
