I'm sure this has been asked and answered somewhere before but I have tried going through this thread several times to find the answer and between all the posts, links and what not I keep getting lost and not finding an exact answer. I have a 2000 2rz I'm getting ready to put in my '80 pickup. What is absolutely necessary to wire in for the swap to run properly. Basically I am looking for what is necessary to wire it stand alone. I will install the a/f and o2 sensors, cat and evap equipment, but is it necessary to wire in the gauges or can I just run mechanical gauges? I have a buggy dash with no speedo (just aftermarket gauges) that I'd like to swap in at the same time I've got the truck torn down. Anything else I should be aware of before I start this mess? Thanks in advance for any help.
