strange box in engine compartment

[josh_t]

my b210 has a small rectangular box attached to the back side of the passenger side strut tower. it has a counter on top of it like and odometer. it has 4 wires coming out of it. it has a relay inside that operates the counter. it doesnt affect starting or running. will post pics of it when i get home.

its a bomb, run!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

It's the EGR counter. It's sole purpose was to turn on the EGR warning light every xxx number of miles. US regulations at the time required the EGR light to come on at something like 60,000 miles, because no one knew how long the EGR would last. Totally useless piece of equipment unless you're going for the "full stock" look. Most '75-77 Datsuns had them, but not all.

i was going to say that :rofl:

[josh_t]

thanks guys. is there any way to test it? cuz i kinda like the idea of all the indicators on the car working right. for instance, i hooked up the seat belt switch and buzzer again. i would like to use that light for something else. like how honduh guys like to use different dash lights for a vtec light. any ideas?

[RedBanner]

dope scope?

[ggzilla]

It measures "count" rather than miles. It is four counts per/mile.

 

 

To test it:

 

1. Ensure the EGR dash light is off with Key ON, engine OFF

2. Ensure the EGR dash light is ON with key to START

3. Ensure the light is OFF when engine is running

4. Note the count on the box. Drive several miles and ensure the count has increased on the box.

well i dont feel like testing it now. especially since there is no egr on my car anymore. what are some other things can i use that light for?

[motavated]

Use it as a low brake fluid light. I is smart?

how about put the fasten seat belt light in there or get on of the little cubby things some had, make a back lit ratsun delete panel that would be sick, just run the counter up to 240,000 and the light stays on from what zilla said ,then make up a delete panel to drive the masses wild.

sorry guys tried to do a multi quote. idk how to use it yet. but they are both pretty good ideas. i want it to be some kind of warning or similar light. maybe a shift light. only problem is i dont have anything to run a shift light with.

[Wide14u]

shift light sounds good but i don't know how you could do it

[merlin]

Drop it in a box of special K and tell some fat chick its a pedometer and to get her ass walking till it clicks 1 mile.

[josh_t]

thats messed up lol. i'm not sure how you would hook it up as a shift light. but i know its possible.

[RedBanner]

the two types of shift light ive used ( tuff trucks is load other than that never seen the need actulay seemed kinda ricer)

. msd box option

. after market tach option

mount a tach with a shift light option and run the light to the panel decorate acordingly( unless you plan on putting a carbin fiber sticker on it ) and roll on all shifty mc shifta loty style.

[josh_t]

i'll probably do the tach one. it will be cheaper than an msd box and i need a tach anyway.

[RedBanner]

Lets see that shift light!

[josh_t]

i just got a tach today with a shift light. i cut the wires to the original light and i am wiring up the egr light and testing it tomorrow. other than that its wired up.
