So i put together a video going over, in detail, how we installed and wired the Autometer oil pressure and transmission temperature gauges in our '90 one-ton Bronco Project:
Ive been running around trying to get the '90 done, and havent posted any updates. So here's where we're at:
I couldnt get the brakes to bleed, ended up having to replace the RABS module because it was seized
I had a code for EVP below minimum voltage
Which turned out to be a defective EGR- the nipple for the EVP to seat against wasnt in the EGR
New one installed, problem solved!
I redid the battery cables, so i could add an anderson plug for the remote-mount winch:
and then i finished off the interior, by adding a pair of Autometer gauges; oil pressure and trans temp
Built a standalone harness for the gauges that has one plug for power/illumination, and a second plug that goes to both sensors
Back when i was putting the accessory drive together i installed the Autometer oil pressure sensor on a Tee with the OEM sensor in the factory port
I thought i had a pic of the trans temp sensor, but apparently not. Its in the test port for the E4OD. Pic of it installed on the 96:
While i was in the interior, i pulled the cluster out so we could go full led:
So I figured since I have money & time invested in the engine & trans, I might as well get some gauges to monitor them. Enter a set of Autometer's GS gauges:
Trans temp probe in the usual location; the test port
Built a simple manifold to allow me to use both the stock pressure sender & the autometer oil pressure sender
Working on the wiring harness. Since the GS series are LED, I have a resistor in-line to dim them a bit, so they match the dash brightness
some wires poking out of the a-pillar...
...and gauges done!
Looks like the motor is ~45 PSI cold, and never drops below 20 PSI even when hot @ idle. Haven't seen trans temps above 140º yet, altho I haven't driven it much since I finished em.
