What and where does this rectangular 7pin wiring pin connector connect to?
I can't find anything that fits it or is not already connected to something else.
The round one next to it is the ignition module connection harness. How can I test that as well?
My trouble is no fuel pump unless I jump fuse 6 to fuse 4. No voltage at the main fuel relay.

wish i could get the photo attachment to work.

 

Wow, I thought somebody here would recognize this connector pin and what it's supposed to connect to.
Could it have been the radio? I tossed the radio in the trash over a year ago when I did the blower motor replacement.

 

Sure, Looks like a radio connector on later model cars

And sorry don't have any wiring diagrams for 240's or your lack of power would be easily traced with that info.

 

Thanks hoonk, I wish I had held on to the radio so I could make sure.

Now I'm thinking it's for the cruise control.
I don't have cruise control so the pin connector is just hanging there.
But that's just a guess.

 

As far as no power to #4 fuse I found the yellow/blue wire from the ignition switch module totally lose at the harness connector.
I can give the wire a slight pull and it will slide right out of the module's harness connector.
That might explain the intermittent dying on the road and crank no start symptoms.
Now I have to figure out how to test the connector to see if it is the problem.

 

check out volvotips.com - you may find the wiring diagram you need posted there.

 

this might help - service manual

and here is a copy of the wiring diagrams service manual for a 1993 240.

The rectangular connector is the radio connector which should have nothing to do with anything else.

 

Thanks Lev, but that would mean there are 2 rectangular pin connectors for the radio. There's a longer one on the right of the photo with 14 pin holes 7 of which have metal contact sleeve inserts. That's the longer one and I definitely remember that one does goes to the radio. And then there's the smaller one on the left of the attached photo that I am unsure of. That smaller one on the left only has 8 pin holes total and only 7 of which have metal contact sleeve inserts. Does that smaller connector go to the radio as well??




Thanks Silvermine for the links. Wish I could find info on how to test the ignition switch module for correct output of each pin.

 

I believe there is ONE radio connector...

 

The second plug goes to the external amplifier

And if you could find the green book for 240 wiring - it will have a page that looks like the one attached from the oldest book I have in pdf. It's for illustration, I know it's for a 850.The green book for wiring has the information you seek =

 

again.. try this

In all those Green Book chapters I couldn't find any chapters that dealt with 240s newer than '89. If I remember my '93 ignition switch module has more active terminals than those earlier models. Also I notice the wire color code seems different as well.
But that attached photo of 850 ignition switch diagram is an example of the type of diagram I need for my '93 240.


Spoke too soon. TP32 wasn't shown, but after I typed 'TP32' in their search bar the '93 wiring diagrams and more came up.
Thanks silvermine!!!
And thanks hoonk for the heads up on the second plug being for the external amplifier.

 

honk, is the 'external amplifier' the same as the ignition control module that's bolted to the inside driver's side fender just behind the head light and just in front of the battery?
That's a 6pin Bosch # 0227100124.

 

OK, I see where the ignition control module (unit) is some times referred to as the ignition amplifier unit. However, if that pin connector behind the dash does lead to the ignition amplifier on inside of the front driver's side fender behind the head light, then where or to what does that pin connector, shown in that attached photo, connect to behind the dash?

 

"External amplifier" refers to the radio. Nothing to do with the ignition amplifier or power stage.

 

lev, thanks for the clarification. Still wish I could figure out what that connector is and where or what it's supposed to connect to.

 

It's for the sound amplifier, the big one is for the radio. Neither should affect engine operation.

 

lev, thanks, I was hoping that was the case.

 

What are you trying to fix?

Does the car not run?

Are you trying to get a stereo to work?

Do you currently use a jumper wire between 2 fuses to be able to drive the car?
