So I have a wideband (aem uego, 6 in 1) on the way and a Safc2 coming soon, while I have an idea of where I'll put the wideband....I havent the faintest idea of where to put the Safc2!



the red reprsents my choice of mounting location for the wideband. its in my feild of veiw without being too distracting and it stays below the topline of the dash so theres no legal problems.


but what about the Safc2? one thought is with the bracket below the radio in the change cup, but i'm sort of fond of a dish for odds and ends.

another though is in the glovebox or the armrest cubby, but i think visible is good since i'm new to using this.

someone else suggested above the center vents, but that just screams STEAL MEE!!!

and finally molding it into the space below the radio. i NEVER use the cupholder in there at all, but i'm not sure if i have the vertical room to do that.

Why are we looking at interior of GEO PRISM???

because thats what i drive?

shares the drivetrain and a bit of suspension with the Celica ST, and is the Corolla's twin.

would the safc fit above the vent to the left of your steering wheel

someone else just suggested that, i'm not sure if it will or not, but i'll consider it.


i'd prefer not to make any holes in my dash or have it too easily seen, but that spot is in the running. i'll have a better idea when i have it in my hands.

any other inputs or suggestions?

mounted!

maybe you can mount the safc ii in your sun visor???
or maybe even in front of your ginormous engine temp guage??

not to be an a-hole, but wtf.

yea its huge alright. i'm not sure why its that big, but that needle can move fast. the 5spd guage cluster with the tach combines the temp on one 1/2 and the fuel on the other side with the tach where my fuel guage and the speedo in the same spot. so i'd assume thats why my temp guage looks soo friggin big.


too late

so ive NEVER had any odd high pitched wine in the car, until today. i had finished installing the wideband and bam, whine.

at 1st i thought it was the wideband, but then i turned off the headunit so i could listen better. the noise of from the HU itself, whever its ON, not just when its playing music.

so its coming through the speakers only when...
the HU is on
the guage is plugged into power and grounded (guage on)

for power i used the cig lighter power or the hazards power, both are keyed to the ignition and on when the car is on.

i just spent 45 minutes in my car with the doors closed and windows up, sweating like crazy. heres what ive found...


the whine is NOT present when the guage is directly powered and grounded to the battery
the whine IS presesnt when the guage is powered from the battery and grounded to any ground wire coming from the dash area around the stereo or the frame near the stereo.
the whine IS present when the guage is grounded to the battery and powered out of the dash.
the whine IS present when the guage is powered out of the dash and grounded to the frame


i'm getting stumped here. is there something wrong with the guage thats making my speakers whine? what could i put inline with the guages power or ground to kill the whine? i was thinking a small cap for some reason would do it. but i'm not really an electrical engeneir, so i really dont know. i really need some input on this! its ear peircing high pitched, not loud but the high freq hurts the hell out of my ears and brain. it feels like my brain is gonna turn to liquid and drain out of my ears!

4.902kHz signal at .25V AC. my front speakers have 'super tweeters' which are very sensitive, they go all the way upto 70kHz

anyone have any ideas on what i can wire in to kill the signal backfeeding from the guage?


or anywhere else i can tap the power from for the guage thats switched to the ignition when the key is ON or ACC?

so does anyone have a suggestion in regards to solving the problem?

My three suggestions:
remove vents and mold into the panels. or just set in front of the heat gauge.






and your problem: sounds like something is interfering with the signal to the radio, through the gauge. i would source an alternate power source from somewhere in the engine bay, then come through the fire wall, away from the head unit. i would think that would solve the problem.

i.e. pull power from the engine bay, and then ground to the frame. that should solve it, based on your troubleshooting. .

thanks, i think thats what i'll have to do. i'll have to pickup a relay somewhere and switch it off something switched to the ignition and mount it in the engine bay. jeeze thats alot of work to just power a guage!

theres some spanish saying for this....(my dad says it to me alot when i complain) i dont really know it, but i remember the english translation.

"if its worth it in the end, then the End, justifies the means" or something like that...idk my dad talks alot

good luck man

yea, its nothing i cant do. i'm just lazy

if you say the whine stops when you run both power and ground from the engine bay, then do it that way, just wire it up so it turns on with your clock or whenever the ignition is on.

if that's a bit tricky, you could even put it on a switch, but that means you gotta turn it on and off all the time...


good luck, and as for the SAFC, i have no idea, my best shot would be under the head unit.

jajajaja
