Hi, you're no stranger to danger, are ya? I just finished a 1990 4cylinder this afternoon. You're going to have to pull the motor, or the transmission. Frankly, loosening the engine mounting bolts (2 on each side and accessible through the wheel well and from above) and the bell housing bolts and then sliding the engine forward will allow access to the clutch pressure plate and throwout bearing. Hang the motor on a chain for the duration. You'll also need to remove the radiator and fan, to allow for that forward slide. It's easy and only seems daunting. Don't forget to have your flywheel turned if it has any grooving (about $30)and to have the machine shop tell you how much he shaved off. You'll need a shim of the same thickness (probably .025, or 25 thousandths)to keep the flywheel in the same spot within the engine system (yep, you need to do this if you have a hydraulic clutch) and don't forget to keep the bellhousing bolts in the right order, as some are longer, etc..than the others. You may, or may not, need to remove the smallish second oil pan, or pickup pan, to allow great access). So, you can do it yourself, if you have the right work area, or, you can pay a shop and have a much smaller headache...as with most vehicular decisions, it's just a question of money. Good luck.
According to the wiring diagram, there is no inertia switch. There is only a relay switch in a 1991 Isuzu Trooper.
