60/40 is the percentage each part of the seat takes up. The drivers side seat is 60% because of a fold down arm rest usually, and the passenger seat is 40% because it's only a seat.
I have a seat from a 93 in mine. It's a solid bench but has headrests and fold down arm rest in the center.

Ok, finished the 3g swap last weekend. Just finished installing a 50k HEI with some new wires and plugs. Got everything timed and all is well in toon town.
Now I have this MarkIII fan and a 200amp solenoid (looks like a starter relay) staring at me and wondering when I'm going to install them.
My question is I want and prefer to have the control over my fan and fan speeds. I do not want anything to come on automatically. I actually prefer this and it is one of the reasons why I want to get rid of my clutched fixed fan. I would like my truck to have the ability to warm up and then I manually turn the fan on low at my desired temp. Should it get hotter I could then switch it to high.
In my ideal world I will buy a three posistion switch (off, low and high) and install this set up in my rig.
Is there someone reading this that could sort of give me a wiring for dummies lesson on what I need to do? Also do I need something more then the 200amp solenoid and the switch? I know it sounds stupid, but yes I really do need my hand held whenever it comes to wiring.
Thanks in advance,
Andrew

You would use the 200 amp solenoid for HIGH and another relay (Bosch 40 amp) for LOW.
For the BOSCH:
30 is battery IN
87 is Power OUT
86 is ground
85 is trigger IN... so Key-on voltage to toggle, triggered wire from toggle to 85
Use an On-OFF-On toggle.

Bosch 40 amp relay.
Outstanding, thats is what I was missing. Also I like the on off on switch too, that will make it nice and easy.
Thanks allot Josh, those were the answers to the questions I had.
Once I track down the bosch I will get this bad boy installed and move onto the next little goodie.
I love the information I have found on this forum and the help from its many great members, my truck loves it and them even more.

The 74 black truck has the MarkVIII with the toggled High and Low. It's never been an issue for me as far as paying attention to the temp gauge and switching on LOW. I have never needed HIGH speed so far in any situations I have been in. Also, when I have switched on LOW I usually just leave it on and let the t-stat regulate the temp. With a 195 t-stat the temps hold a steady 198-200, stop-n-go or highway. As a matter of fact I can usually turn the fan OFF when I hit 50+ mph and still hold the same steady temps.
Beat that FIXED MECHANICAL FAN!!!
All kidding aside... I do plan on also converting my 87 Ranger to the MarkVIII, but likely will do an automatic LOW and switched HIGH... why?
Just because really, something different. Also, with the issues of the 2.9 V6 cracking heads I may run that engine cooler (185 or so) than I usually preach on here.

But then again those continuous duty solenoids are fairly cheap and bombproof, might be good to use in the long run over Bosch's.... But the Bosch's can be bought at any parts store.

The 200amp is what I had laying around from some farm equipment we were working on so I figured it would work and set it in the markiii pile to wait for its turn to install.
Picked up the 40amp relay today for the low.
Will get started here shortly on the swap.

Just a theory. I also think the temperature "probe" needs to be submerged in the coolant and not just located above the flow where it doesn;t get full contact like the stock location.
I have used the input heater hose before and it worked quite well, always submerged and a constant flow of heated coolant.
Do not use the return hose from the heater core for obvious reasons. The only caveat is having to run a ground wire to the sender when it is spliced into a rubber hose.

Excelent wire diagrams on this link.
Mark VIII & SPAL V3
read post 28 and post 33 on page 2. one diagram shows how to have Light LED
indicators when fans are on for high low and AC

I don't have the same type of temp probe you're talking about, but I do have the probe on my thermo switch fed halfway down the top radiator hose (basically the same position your talking about). I fed it down the hose and made sure it was sitting on the bottom side of the hose. My fan cuts on and off just fine with it set up this way. Then again I'm running a pretty stock 302 and you have a 460.

im an electrican, i have no problem wiring it. i didnt think about the coolant not hitting the sensor in the t-stat neck. which way does the coolant flow? does it go to the radiator in the top hose ? or go from the radiator to the engine in the top hose?
