Just by happy accident I found this link to the Ford Ranger WL/WL-Turbo 12V SOHC engine service manual:
http://cid-1fcf8fc855aa51e7.skydrive.live.com/self.aspx/.Public/RANGER%5E_DRIFTER%5E_FRONT%5E_PAGE.zipShould be the same for the Mazda B2500, since they share the same engine & chassis.
Download it before it's gone. Hopefully someone will find this thing useful.
If link doesn't work, PM me and I'll upload a copy to Rapidshare for you.
Just in case you guys missed it, here's the
WLC 16-V DOHC TDCi engine service manual too (for Ranger & BT-50)
Enjoy it, galaxy rangers!!!
