Looking for wiring diagrams (turn signal wiring harness, anything related to under the dash) or a comprehensive FSM

[Inherited Thunderbolt]

I am in the process of replacing the steering column assembly in my truck. In the process of extracting the old column and transferring parts, I have run into two problems: first, there was an aftermarket alarm that is no longer functioning, wired into the car in an obviously-incorrect way (at a minimum, the clockspring wiring harness had been spliced to interface with the alarm; I assume there will be additional blunders here but I don't know). Secondly, the turn signal wiring harness fell apart on me; six of the seven wires fell out of the harness and I don't know where these wires are supposed to be.

I am attempting to track down wiring diagrams for everything under the dash so that I can figure out how to pull the alarm without possibly disabling the vehicle, and so that I can fix the turn signal harness by correctly replacing the pins in the correct holes. Ideally, I'd like to get full access to a FSM to help me with work on the truck in the future (I also have problems with the power mirrors, fog lamps and horn, and the aftermarket stereo and subwoofer were wired in without consideration for routing or appearance). I have managed to find these before for cars I have owned previously, but for this truck there's a higher signal-to-noise ratio; I ended up downloading something purporting to be the FSM for my model year, but contained a teardown for the OHV engine, which my model year does not have.

I'm wondering if anyone can point me to a source that has a full wiring diagram; at a bare minimum, I need to find the configuration of the leads for the turn signal wiring harness.

You need the EVTM (Electrical and Vacuum Troubleshooting manual) for your year model. You can usually find them in paper or on disc on eBay.

You need this one: https://www.ebay.com/itm/2002-Ford-...448672?hash=item48e5d2e3e0:g:QHoAAOSwGRFeyu9q

Must be for 2002, assuming thats your Ranger year, and from the Ford manual set for that year and for Ranger
It covers all Ranger sub-models for that year, and all options

Used to be called the EVTM(electrical vacuum troubleshooting manual), I think it changed to "electric service manual" in 2001

A lot of local libraries have an AllData type program available on their website for free. Which would have the wiring diagrams and troubleshoot info for the truck.

Thanks for the assistance everybody. This looks like what I need. I checked my local library Roert42 and unfortunately all they have in the online collective is the Haynes manual which I already own. I'll see if I can find other service manuals using another county's alldata. I can also check my alma mater to see if they have one; I didn't think to use the library to try to track these down.
