if your battery is on the firewall it makes it very difficult to install any heater--not much room. it can be installed in the center or center right, but beware if you have to remove floor boards it gets a little tight. enought about the problems take the heater and hold it up around where you might want it. do a little relationship thing so you can see what is on the other side of firewall. make a template of the mount holes and the water outlet/inlet and use this to drill holes in the firewall.
