1993 Bronco Wont Shift please help

[Bmarlowe30]

I don't have that module anywhere. mine has no power anything as in windows, seats etc.

Model 230

97dB(A)

12VDC these are the numbers on that alarm thing

 

[miesk5]

Yo,

OK on the 4wabs module.

Did you find the harness connector that needs to be jumped?

That back up alarm should be disconnected and stored for now if you want to keep it after the bigger issues are solved.

 

[Bmarlowe30]

No I don't have that. I went to ford cause I have a friend who is the parts manager there and we looked it up mine has rear only abs. and does not have that large plug you pictured in. it has that small plug to the black box for the 4wabs. would it be that and if so what wires?

***** the backup alarm that is stupid. I cut the wires to it

 

[miesk5]

Yo Brian,

On page 1, I posted a pic of the connector by turboghost showing what needed to be jumpered.

Did your friend explain why the 4wabs HCU is in there? Because

Rear abs (RABS) was in 87 through 92 Broncos and those years did not have that HCU.

Are you sure you have a 93 and it's not a 92?

 

[miesk5]

Yo,

Here is a pic of the RABS Valve in 87 to 92 Broncos:



Does that look like your two pics?

 

[miesk5]

Yo,

I see that you are still logged in so here are the 93 Bronco 4WABS Brake Wiring Diagrams;

[Bmarlowe30]

yea we went off the vin number and it listed everything that came on that bronco

and no mine is different that that. on the tag on the door says it was built in 08/93

 

[miesk5]

Yo Brian,

OK. I am wondering if Ford used left over RABS SYSTEM on your early 93 model year (MY93). FORD did this in other years for different parts or systems.

One more look... do your 2 pics on page 1 look exactly the same as I posted for this 4WABS Hydraulic Control Unit (HCU) pic by Steve? Here it is...

[Bmarlowe30]

in the first picture I have the same pump but do not have the plug part

in the second picture I do not have that nodule at all.. and I have the whole dash out right now to where its just the wiring harness plugged up

so I can test grounds and continuity of wires

 

[miesk5]

Yo,

Here is the 93 Bronco Dealer Brochure.

https://drive.google.com/file/d/0B-xGWnnLeWl6cGFMTDNNcGprQTA/view

By Ford via FROGGMAN who has a 93 with 4WABS

It shows 4WABS as standard on page 8, under functional.

Once we get this cleared up, can get it working & you'll be cruising!

Yo Brian,

I didn't see this until I posted the Brochure.

OK, first pic is a 4WABS HCU (PUMP)

2nd pic is RABS MODULE.

 

[Bmarlowe30]

I have that pump but not the module or that plug

 

[Bmarlowe30]

so even if I found that plug somewhere I have no where on the wiring harness to plug it into

man I wish I could catch a break on this thing

 

[miesk5]

Yo,

See this diagram

Did your dealership friend use the correct VIN when looking up as built info?

 

[Bmarlowe30]

yea he did I brought it to him. he has been there for 25 years and runs the parts department. he is really good.

I found an interior wiring harness specific to that year on ebay for $80 so I bought it.

it just came in so I'm gonna put it on this week and see what happens

sorry been MIA a couple of days I have been helping people working on their cars. now back to mine lol

 

[Bmarlowe30]

harness wont let it start so its not the right one YAY

I really appreciate your help Meisk you are the only one I have ever even gotten to reply to me

the old harness I think has a grounding issue. the blsck plug on the back of the instrument cluster has like 6 wires that show continuity to ground.

could the plug itself be bad?

 

[miesk5]

Yo,

OK,

Does starter relay click and:

Starter cranks but engine does not fire and run?

Or

No relay click?

Here is the Wiring Diagram for start circuit;

Do accessories such as the radio work with key in accessory position?

Frame & Battery pic in a 93;



"...With the wheelwell gone, it's easy to inspect the frame ground, just inboard of the spring tower on top of the frame rail. The battery ground cable is stripped ~3/4" and a tab is soldered on so it can be bolted to the frame..."

 

[Bmarlowe30]

it cranks over just does not fire. it starts with the other harness just wont shift. and ground is good

 

[miesk5]

Yo,

OK.

I have a crank, but no run article, but it must be in this harness.
