Wiring Diagram Issue

[Tommy Gun]

Looking in a Haynes manual at the wiring diagram for a SN95 it is incorrect.

It shows 21 wires coming out of the instrument cluster, I have 26 coming out of mine.

Some wires are the same color, but about 10 wires are different colors that don't show in the book.

I'm trying to find the speed sensor wire that goes to the speedometer, but can't get under the car far enough to find/reach it.

Anyone happen to know another source to find a wiring diagram?

:wow2: I saw your name next to the thread and almost didn't click it for info. :rofl3:

Thanks, I'll look through it and see if I find what I'm looking for.

Why are you wasting time with a Haynes....? Their useless books.


Great link jeff...

I think those extra wires were for the "Wall Detector" feature that you didn't have installed on your car. :haha:

Where should I find a wiring diagram?

I couldn't find the speed sensor wires in Jeff's link. :nonono:

I'd look on EBay or Craigslist for a shop manual for your car.

This image in Jeff's link shows the Vehicle Speed Sensor wire as Gry/Blk like my Haynes manual.

The problem I'm finding is that there is no gry/blk wire going to the speedometer whatsoever. :banghead:

Www.helminc.com

I need to search my threads....JD posted a link for my 11 manual that actually brought up pages to view. Just changing the year car should do the same for you. Helm is where I buy all my manuals.

Awesome site, Jeff -- thanks :tiphat2:

Using this thread for a wiring question. I’ve heard before that aluminum wiring can be bad, guessing when overloaded more so than copper.

But see it is permitted is some instances. When we had a hot tub is was run w 220V 8ga 3 wire plus ground aluminum to the far end of our house. No issues.

So I ran a camper outlet today. 30 amp, 120V. Called for 10Ga. I used the old hot tub wire. Figured since it was so far away, the 8 would be okay and probably better.

But will I see any issue w it being aluminum?

The key to aluminum wiring safety is what you do where it meets copper. There's nothing inherently wrong with aluminum wiring BUT you MUST use connectors specifically engineered for Al-to-Cu connections, else the copper WILL corrode the aluminum where they touch and as that corrosion builds the resistance of the connection goes up and up and with that the heat goes up and up until it either melts the connection or eventually causes a fire.

I would definitely check with the local code and even an electrician on this one. There are several issues.

I recall aluminum being used in larger gauges like when running a big sub-panel (it's definitely used in the primary transformer-to-house drop). What I'm not sure of is whether there is a 1:1 correspondence. Ie, is 8-ga AL the same current carrying as 8-ga CU... I also recall that everywhere I used AL, it was 8(?) or higher, and also twisted composition. So I'm not sure if the application you have is correct.

You also need to dope both ends of the connection - the breaker in the primary panel and the connections in the plug (unless it's marked CU-AL, see below).

Aluminum house wiring was used for a while but eventually replaced. It could over heat but it was at the dissimilar metal junctions. I recall seeing AL-CU pigtails with special twist locks and dope to prevent oxidation. Most newer fixtures have a stamp on them "AL-CU" if it works for both.

AL always scared me and I always just ran the cable and let my electrician make the connections.

Yeah, Tony, it’s not a direct map gauge-wise. You need a larger gauge (smaller number) Al vs Cu but the 8 ga aluminum should work fine for a 30amp (10 ga copper).

Some connections can just be doped but not all. It depends on the fastening mechanism. Imo, much safer to use an engineered Al-Cu connector. They are engineered and are usually packaged w/ instructions.

Also it’s much easier to nick Al such that any flexing can cause a strand to separate over time (esp if the Al has to be bent/manipulated some) thereby reducing the effective gauge. More care needs to be taken when stripping Al cables.

I'm opposed to using this thread for an AC home wiring problem. If I were a moderator, I would move it.

Whew, didn’t get banned. :yay:

If only we did have a moderator who would step up and move the new unrelated content to a new thread where it belongs. :look:

[68fastback]

Gee. That would ruin everything :biggrin:

Yep, good thing were not that "official: here

[Tommy Gun]

So, I just spoke to the opener of the thread and he said you all can suck it. The thread is called wiring issues and that’s why he picked it.


I’ll ask him exactly what it is he wants you to suck.

Did this happen?

[Tommy Gun]

No. Sold that car and made money. Lol
