Well, I will throw in some info here as well, for when this gets archived. The 10K ohm tach mod recommended for the V6 tach also works great on the I4 tach... You do have to turn the calibration pot a tad so it will read accurately.

This would seem to suggest, for you SR5 cluster swap dudes who can't find just what you need, that an I4 tach will work on the 3.0 V6 as well, or vice-versa (same year application of course).

RE: oil pressure gauge, be sure to use WHATEVER year/model sender matches your gauge.
