Wires

[DiscoPhoto]

Few questions that aren't answered easily without looking under a correct truck


95 D1
Speedometer cable goes from the t-case to the transducer to where? Mine is missing after my swap
CDL sensor wiring goes from the t-case to where?
Where does the wire that plugs into the reverse light switch on the transmission originate from on the body?

 

[discostew]

What are you working on ? I would think the cable would go to the back of the speedo eventually .

95 d1

Damnit, there's a 15 page thread about people's hurt feelings on driveshafts, but nobody knows where any of these wires are routed?

That thread is AWESOME!!!!!!!!!

I really don't know on a D1, but I would imagine that the wires would go to the fuel injection ECU as they would on a Defender.

Agreed...

I'm going to pull apart a D1 to figure this out aren't I.

On my 95 D1 the wires plug into a plug by the brake master cyl

Zach's truck is a 300 Tdi though, so no ECU. Must plug into the harness for the speedo somewhere.

Right, but it was a NAS V8 truck.

Right, but it was a NAS V8 truck.

So he would just bypass the fuel injection harness and go right to the speedo with the signal from the transducer?

My 93 LWB started as a gasser.
I removed the ECU and all associated harness.
Is my speedo different from the '95 D1?
My cable just attaches to that signal converter box thingy and I assumed goes to the guage.
Works great.

Just stick a GPS on the windshield.

Exactly, I just need to find the transducer

(which Jeff refers to as the little box thing)

I know where it is on a NAS Defender, but not sure on a disco.

I thought the VSS attached to the transfer case is the transducer?

It could be on the later ones, I know on the earlier ones it was chassis mounted. That's why I'm trying to find out where the wire goes from the t-box

Pretty sure my 95 had the VSS with no other transducer. The LR part number YBE100540G is for all '94-99. However, RRC's (except 95) had the external transducer mounted on the driver's side frame rail near the engine, connected via normal mechanical speedo cables.

This page from the factory manual shows the 300 Tdi with the same VSS on the tc as the V8's:

[aliastel]

Do you have a speedo cable coming out of the rear output housing of the tc?

 

[DiscoPhoto]

I only have the VSS on the t-case, nothing else. I also don't see any wires whatsoever hanging anywhere that I could connect the VSS to.

 

[aliastel]

There should have been a wiring harness you unplugged from the VSS of the original transfer case. The new one should plug right into that.

I know, unfortunately I'm not sure where that is at this point. I removed the drivetrain in June or July, and put the new one in last month. I must have cut or pulled the wiring.
