intermittant wiper relay diagram?

Hello, I am trying to install an intermittant rear wiper relay in a car which doesn't have an intermittant rear wiper - it currently has a switch, whereby you switch it on and the wiper wipes constantly. I have been given a relay from a Vauxhall Astra which controlled the intermittant rear wiper - it's an Italamec 90 240 092, and has the following five terminals; 15 31 53e 53c I Anyone have any idea what each one of these should be wired to? All help appreciated - thanks! Oli.

Automotive component pin assignmentsYes, it's perfectly true. All those little numbers barely perceptibly cast in the bases of automotive relays are standardized!

Terminal Designations (Excerpts from DIN Standard 72 552)The terminal designations do not identify the conductors, because devicewith different terminal designations can be connected at the two ends ofeach conductor. If the number of terminal designations is notsufficient (multiple-contact connections), the terminals areconsecutively numbered using numbers or letters whose representationsof specific functions are not standardized. <<huh?>>Terminal Definition-----------------------------------------------------------------------IGNITION1 Ignition coil, ignition distributor, low voltage-----------------------------------------------------------------------(Ignition distributor with two separate electrical circuits)1a to ignition contact breaker I1b to ignition contact breaker II-----------------------------------------------------------------------2 short-circuit terminal (magneto ignition)4 Ignition coil, ignition distributor, high voltage-----------------------------------------------------------------------(ignition distributor with two separate electrical circuits)4a from ignition coil I, terminal 44b from ignition coil II, terminal 4-----------------------------------------------------------------------15 Switched + downstream of battery(output of ignition/driving switch)15a Output at dropping resistor to ignition coil and starter-----------------------------------------------------------------------GLOW PLUG AND STARTER SWITCH17 Start19 Preheat-----------------------------------------------------------------------BATTERY30 input from + battery terminal, direct30a input from + terminal of battery II(12/24 V series-parallel battery switch)31 Return line to battery- battery terminal or ground, direct31b Return ine to negative battery terminal or ground, via switchor relay (switched negative)-----------------------------------------------------------------------(12/24 V series-parallel battery)31a Return line to - terminal of battery II31c Return line to - terminal of battery I-----------------------------------------------------------------------ELECTRIC MOTORS32 Return line(Polarity reversal possible at terminals 32-33)33 Main terminal connection(Polarity reversal possible at terminals 32-33)33a Self-parking switch-off33b Shunt field33f For second lower-speed range33g For third lower-speed range33h For fourth lower-speed range33L Counterclockwise rotation33R Clockwise rotation-----------------------------------------------------------------------STARTER45 Separate starter relay, output;

When in doubt, try it out !

What's this, ISO list twice in a week? The last one started with me being pedantic about 86 being the pos coil side, thanks Craig and Kevin, joking aside thanks John, I'm going to file this.  Zcacogp, be very very careful if this is the current shape Astra, it's all data at the switches contolled by front and rear fusebox processors. You really have to go to the front fusebox to pick up a solid 12v+ ign supply (Black in a loom going behind the battery).

Just thought of something that might be relevant. UK Fords of the late 90s had the intermittent rear wiper relay mounted on the underdash fuse box. When no such facility, there was simply a bridging bar across the connector terminals, if pre 05 your Astra might have that, also look to right hand rear over wheel arch, I'm sure that on some Astras there was a plug-in facility there.

Dear Oli, I am not an expert in wipers, but I´ll try to help you. In order to to what you want first of all you have to check your motor connections because you have to identify 53e terminal. this terminal is a signal that is originated from the motor to the controller. L15 you connect to switched battery, L31 to GND, 53c to the (+) of the windshield wiper pump, it is an input to your controller, 53e you get from your motor, I is the signal you have to provide to turn it on, I suggest you just add a switch and connect the other side together with L15. I hope it helps. Cheers, Celsoautomotive electronics designer
