I know this does something under the hood of my 1973 240z....but what...? And where can I get a new one...? Thanks...Ryals

What are the wire colors on the engine harness side?

On firewall near wiper grommet right?

I believe it is the "Throttle Opener Relay" Part 18 below:

 

 

 

 

Is there any chance you can read the part number on it? It looks like that is unlikely.

JIDECO is the brand name. The model number is so faint on top that it cannot be read. JIDECO is stamped, the model number is printed. I thought this might be a relay for the electric fuel pump near the gas tank. It has a four prong connector. The wiper relays I have seen only have 3.

Wish I knew where it was mounted under the hood...!

Mine is found under the righthand side of the dash on the relay panel that mounts to the passenger kick panel. 

It has part number 25230-89914 which is an intermittent wiper relay. 4 prong connector with 3 wires.

Discontinued by Nissan but I did find this https://zparts.com/index.php/product/240z-intermittent-wiper-delay-relay-25230-89914/  $75 seems a bit steep to me.

I hope that helps some.

It is on the firewall between the battery and choke cable  gland

Any proximity to the thyroid gland? 

Autocorrect can be a PITA!!!

PITA bread...is food for thought...!

So now I would like to find a new one...any idea what the part number is...?

(the intermittent wiper relay is a 3 wire connection, this is a 4 wire)
