Hello,
We know on our D -Jetronic harness some male connectors 2,3,4,5 ways with female connectors with female pins inside. (IMG:http://www.914world.com/bbs2/uploads_offsite/i48.servimg.com-23807-1640445696.1.jpg) Do you know female connectors with male pins inside. ? I need your help because I want to use on my 914 Porsche a 123 ignition distributor. For the OEM distributor I have a 3 ways female connector and for the harness 3ways male connector I'd like to make a little harness with a 3 ways male on one side and 3 ways female connector on the other side It's easy to find male connectors with female pins but I don't find female connector with male pins. Do you know where I can find these parts ? The advantage of this little harness is if I have problems with the 123 ignition distributor I can use my OEM one without harness modification. Can you help me please ? PS: what is the item number of these D-Jetronic connectors ? Best regards Michel |

While these connectors have some good features, me no likey them for a weather-exposed, hot engine bay environment.
Heat and fluid contamination kills exposed wiring. A short section of the wires are exposed where they enter the connector housing and heat shrink on the harness, and each entering wire has no stress relief at the entry point. Its a vulnerable condition susceptible to wiring degradation. |

A short section of the wires are exposed where they enter the connector housing and heat shrink on the harness, and each entering wire has no stress relief at the entry point. Its a vulnerable condition susceptible to wiring degradation. Gotta disagree with this. Deutche connectors are 100% acceptable. This style of connector is widely used in automotive wiring by all OEM’s and has hundreds of milllions of miles proving out its durability and acceptability. I’m taking about all kinds of shaker table, laboratory, and real world on-road testing backed up by known warranty costs and field failure rates. The individual wires ARE strain relieved by the pins. There is a crimp to establish electrical contact. Behind that crimp is a second set of “wings” that roll around the wire insulation - acting as a strain relief to the electrical crimp and supports the wire as it exits the connector body. Trying to make an additional strain relief out of heat shrink causes nothing but endless trouble. The heat shrink “strain relief” then causes the pins to break or to be pulled on by the added weight of all the heat shrink on the wiring and results in pins being pulled out of the connector body at best or intermittent electrical connections which are the the worst since intermittent issues are terrible to troubleshoot. When I did DoD work, we could not get this through the heads of some that just don’t understand automotive wiring, or those that don’t appreciate how much development, testing, and validation have gone into modern automotive wiring over the past 50 years. The defense company I worked for actually lost that contract due to the multitude of issues the program had related to wiring. 100% of which were self created by people that thought they were doing the right thing by adding “strain relief” and refused to understand how these connectors are designed to function.

Gotta disagree with this. Deutche connectors are 100% acceptable. To clarify my concerns, * No strain relief. Understood the strain relief provision at the point of the wire to the wire terminal which is concealed within the housing, no issue. The location of concern is where the wire to the free-hanging connector enters the housing. The connector design provides no strain relief here as does the boot on the D-Jet and L-jet harnesses. Movement of the wires over time as they deflect relative to the housing creates a fulcrum and stress concentration and ultimately a failure. Its a weakness of this connector design for long term durability in my experience. * Exposed wires where the wires enter the housing. The housing design allows no provision to protect the short section of exposed wires from where the harness casing ends and where they enter the housing, from heat and fluid contamination in the engine bay as does the boot on the D-Jet and L-jet harnesses. Both of which will ultimately cause a failure in my experience. https://www.youtube.com/watch?v=GQs7EPzDOak These two failure modes are the majority of the engine bay wiring harness failures I see from examining thousands of older, worn out engine bay harnesses with presumably gazillions of billions of miles on them collectively (creative huh (IMG:style_emoticons/default/laugh.gif) ) This Deutche style of connector provides a good sealed connection (although its a complicated multipart connector), but its interface with the wiring on the harness is not resolved for long term serviceability in a weather-exposed engine bay environment. If you ask me, I think there need something like a silicone boot between the connector housing and the harness cable. Attached thumbnail(s) ![]() |
