1993 Front Harness Annotated Connector Pictures
 

Two weeks ago, I posted asking for this information and I was basically told it didn't exist and to read the electrical manual. Last weekend I took the time to make the images I was looking for. I figured that people, like me, looking to scale down their front harnesses could benefit from actual pictures of the connectors and spatial perspective of where they are located on the harness.

Having this would have saved me hours of work and is a great supplement to use with the electrical manual availible here:

Hope it will help you guys out too

awesomeeeee post! will use this in the future!

Sticky FTW.

Nice!

EXCELLENT job. Really like the clear annotations!

Dale

Nicely done. Thanks.

Awsome. I know that took a lot of time to put together. Thanks from all.

Here is a pic of the emission harness that another forum member did for us. If someone could post a pic of the engine harness this thread would be complete and fantastic for all. One stop shopping.

^^ that is the engine harness.

Here's the Battery Harness.

Here's the coil harness diagram:

Maybe I'll do the dash in a few days. Since it's one of the last.

Grimple1,
Check the FSM. It refers to the harness I posted as the "Emission Harness (EM)" and yours as the "Engine Harness (E)" not the battery harness. The OP covered the "Front Harness (F)". I just wanted to keep the names as they are referred to in the FSM to limit confusion. Ref page Z-7 in the 94' Wiring Diagram manual.

Steve.

Need larger version of the battery harness or whatever it is! Can't make out the text! =)

GREAT JOB!!!!!! this is handy!

fair enough. I've seldom heard anyone refer to it as the "emission harness". Everyone just naturally calls it the "engine harness" (even when purchasing a new one from the dealership). :icon_tup:

Several people have asked for a larger version of the Engine Harness. When I originally posted it I thought I was at the file size limit but I'll see what I can do to make it easier to read. I'll post it to this thread.

Jeff

This could have also saved me hours at one point!! Great to have available for quick refrence.

good work

added to the FAQ

uploading photos in case things on photo bucket change....

Thank you gentlemen. I'm happy that my work is FAQ worthy :)

A very valid next step should/could be to create the connectors/shapes in Visio and draft up some basic harness-designs with basic modifications (removed emissions, etc).

I just wanted to add this since there was some confusion with the harness names.

I redid the lettering, hopefully it is more readable now.


Jeff

Very good info, thanks for putting this up! If only I had access to this a few weeks ago when I was wiring my motor :P

Since we're not allowed to edit posts..... Here are two corrections:

Block (1)
B1-10 – Condenser (NOT AC Condenser like I listed above)

Block (2)
E1-05 - Headlight Relay (Missing above)

Sorry about that
Lane

Still curious about this particular one - auto variant - should be in sector "3".

Know it's been mentioned on here before too!
